3003 aluminum tubing range of applications

3003 aluminum tubing is the AL-Mn aluminum alloy, it is the most widely used in rust-proof aluminum, the strength of this alloy is not high (little higher than the aluminum industry) can not be heat strengthened, so the factory need to use cold working methods to improve its mechanical properties,in the annealed state has a high plasticity, in the half-cold hardening plasticity is still good, when the plastic work hardening is low, good corrosion resistance, good weldability, machinability bad.
3003 aluminum pipe formability, welding, and corrosion resistance are good.  Many componet parts the require need good formability ,high corrosion resistance and good solderability ,so use 3003 aluminum tubing is best choose.some products need to have a high strength alloy than 1XXX grade service work,

3003 aluminum pipe almost use in industry such as kitchen utensils, food and chemical products processing and storage means, tank transport of liquid products, tank, pressure vessels and piping general objects with sheet metal processing, heat sinks, makeup board, photocopier rollers, ship timber.

China’s aluminum exports will further increase

According to the futures through network “report, by the unexpected yuan depreciation, China the original expansion of exports of aluminum material will receive a further boost. China is the world’s largest producer of aluminum plate.

Goldman said that despite the decline in aluminum prices, many manufacturers have not cut out, partly because of the government’s subsidy policy. At the same time, China’s domestic demand is weak, has stimulated a large number of aluminum exports to the global market. 1-7 this year, China’s aluminum exports rose 28% year on year to record high. And this week the people’s money devaluation, aluminum market will face more supply, because people Za weakness will reduce domestic production costs.

Briggs BNP, an analyst at Paribas Stephen in Paris, said: “it is very clear that bad, which reduces the cost of domestic dollar denominated production.” LME this year three months aluminum fell 14% to $1589 per ton. According to the harbor intelligence data, in the Chinese devaluation people Za 1.9%, the average cost of production per ton of raw 2024 aluminum plate reduction of $12 to $1728. The company expects 10% against the dollar, people’s money, will further reduce the cost of $50 to $1678 per ton.
According to customs data, as of July this year, China exported 2870000 tons of aluminum and aluminum products this year, a record high. Harbor general manager Vazquez Jorge said in a report Tuesday: “the devaluation of the renminbi has restored the competitiveness of China’s exports.” “China’s structural economic growth slowdown, production capacity and production will be the main driving force for the decline in commodity prices.”

how many classifications of Aluminum pipes have?

Industrial pure aluminum aluminum content between 98.8-99.7%, but the pure aluminum material is too soft not have too much practical value, alloy aluminum products is based on pure aluminum group in general, the main alloying elements are copper, silicon, magnesium, zinc, manganese, minor alloying elements are nickel, iron, titanium, chromium, lithium and so on. Because of its high strength, light weight, easy processing, good appearance and corrosion-resistant properties, is used in many industries.

Aluminum alloy grades used by four digit naming alloy group ，in order to  the distinction between aluminum alloy content:

Aluminum Alloy Grade	main alloying elements
1XXX	Pure Aluminum (Al content of not less than 99.00%)
2XXX	Cu (Copper)
3XXX	Mn (manganese)
4XXX	Si (silicon)
5XXX	Mg (magnesium)
6XXX	Mg + Si (Mg + Si)
7XXX	Zn (zinc)
8XXX	Other elements

Different aluminum series grades have  differences performance  and applications , the DETECT-METALS  currently produces precision aluminum pipe primarily is  3XXX and 5XXX series, especially in 3003,3103,5049 and 5052, mostly because of its good corrosion resistance and formability, These aluminum pipes is widely used in heat exchangers. Aluminum places 6XXX series based mainly 6061,6082,6063,6005,6110, because of its high strength, easy machining, weldability and corrosion resistance, 6061 aluminum pipe extrusions used in many structural components .

In September this year, China Aluminum will reduce production of 650000 tons

In the news recently, the world’s largest aluminum pipe producer-Detect metals Aluminum said the company and other peers are still considering the reduce of production, following the last two years, 650000 tons of production was recuded, the company will in September this year to cut 200000 tons, so the aluminum price is expected to rise by the end of this year to about $2000 per ton.

For this year’s production plan, China Aluminum in a recent quarterly report said that this year will not restart aluminum smelting plant which has been closed in 2013, is considering the implementation of active maintenance capital expenditure management system, in order to optimize the maintenance of the original, is expected this year’s electrolytic aluminum production will be flat in 2014 of 3601000 tons.

China Aluminum said, plans to improve the construction of facilities in 2018 Mykolaiv aluminum plant, when the alumina production capacity will be increased from the current 1600000 tons to 1700000 tons.

Previously released data show that the second quarter of the 2024 aluminum pipe oxide production of 1818000 tons of alumina, according to the quarter rose 0.6%, an annual rise of 0.8%. Bauxite production reached 3223000 tons, 3.2% increase in quarterly and annual growth of 7.3%.

In the second quarter, the China Aluminum sales and average price fell: during the total production of its total output of 908000 tons, an increase of 0.8% in the quarter, but the sales volume by 5.1% to 880000 tons per season. The average price of the period to achieve a reduction of 7.7% to $2124 per ton, compared to the quarter.

Three new member companies join the Aluminum Association

The Aluminum Association announced the new member companies to join our group heiche surface technology; Phinix, LLC; Walter surface technologies. These companies are joined to the Associate Companies, the supply of North American aluminum sheet industry and goods and services company.

A new member of the increase came to an ongoing demand for growth of al. According to recent data from the Aluminum Association, the North American 3003 aluminum sheet industry in 25500000000, at 2014, the most 2006 pounds of aluminum shipments estimated. Compared with the new data show that the demand for 3.1% years increased to 2015 in April. From the 2009 baseline, the United States and Canada’s metal demand increased by nearly 40%.

“We are very pleased to welcome these new member companies,” said Heidi Block, President and CEO of al. “Our colleagues have brought a unique perspective to our work to help us serve a wider range of industries.”

How to clean stainless steel surface?

Stainless steel bending Notes

1. From unit size, the thicker the plate, the greater the force required to bend, and with the increase in thickness of the device when selecting bending bending force margin should be greater than the average thermal conductivity of stainless steel due to low-carbon steel poor, low elongation, resulting in deformation force required;

2. The next unit size, tensile strength, the smaller the elongation, the greater the force required to bend, bend angle should be larger with respect to the same thickness of the stainless steel bend angle is large, it should be Special attention will be bent or crack, the impact strength of the workpiece;

3. The design of the thickness and the bending radius corresponding to the case, based on experience, expand the size of a bend of the workpiece minus the sum of two right-angled edge thickness, designed to fully meet the accuracy requirements, expand the amount calculated according to the empirical formula simplify the calculation greatly improve production efficiency;

4.The greater the yield strength of the material, the greater the amount of spring back, to get bent parts 90 degree angle, the required pressure of the knife angle must design smaller, austenitic stainless steel in the bend with respect to there is a big deformed steel elastic recovery, so the pressure is relatively steel knife angle is smaller.
