3004 aluminium alloy sheet is the most widely used antirust AL-Mn aluminium alloy.The forming, solderability, corrosion resistance of 3004 aluminium sheet is good. For the processing of parts that require good formability, high corrosion resistance and good solderability, or require both these properties and require higher strength than 1XXX aluminum alloy work, such as kitchen utensils, food and chemical processing and Storage devices, tanks and tanks for transporting liquid products, various types of pressure vessels and piping general utensils, heat sinks, cosmetic plates, photocopier drums and marine materials processed by sheeting.
This aluminium alloy sheet plate is not high strength, heat treatment can not be strengthened, so the use of cold-working methods to improve its mechanical properties: a high degree of plasticity in the annealed state, the plasticity is still good in the semi-cold hardening, cold hardening low plasticity, corrosion resistance ,good weldability, poor machinability. Applications Mainly used for demanding plasticity and good weldability, low-load parts such as mailboxes, petrol or lubricant conduits, liquid containers, and other light-duty parts made from deep drawn working low-load parts that work in liquid or gaseous media: Wire used to make rivets.
The alloy composition of 3004 aluminium is:
Aluminium: 95.6 to 98.2%
Copper: 0.25% max
Iron: 0.7% max
Magnesium: 0.8 to 1.3%
Manganese: 1.0 to 1.5%
Silicon: 0.3% max
Zinc: 0.25% max
Residuals: 0.15% max
3004 aluminum sheet strip is mainly used in the production of chemical products and storage devices, sheet metal parts, building materials, building baffles, cable ducts, sewers, all kinds of lighting components, beverage cans, Langban, building materials, color coated aluminum, electric lamp.
