Aluminum alloy

Aluminum alloy is based on aluminum alloy. The main alloy elements are copper, silicon, magnesium, zinc and 

manganese, and the secondary alloy elements are nickel, iron, titanium, chromium, lithium, etc. Aluminum alloy

 density is low, but the intensity is high, close to or more than high-quality steel, plastic, can be processed into

 various profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used

 on industry, usage is second only to the steel. Aluminum alloy is divided into two categories: cast aluminum alloy, 

used in casting; Aluminum alloy, can withstand the pressure processing, the mechanical performance is higher 

than the cast state. Can be processed into various forms, specifications of aluminum alloy material. Mainly used 

for making aviation equipment, daily necessities, building doors and Windows, etc.

   Forging Alloy Alloy naming System International (International Alloy Designation System) named forged Alloy

 widely accepted. Each alloy is due to a four-digit number, of which the first digit is the main alloy element.

The 1000 series contains at least 99 percent (percent of the weight) of aluminum.

2000 series of copper alloys, strength comparable to steel. Formerly known as duralumin, it is commonly 

 used as a carrier alloy, but it is easily eroded by grain and gradually replaced by 7000 series.

3000 series manganese alloy, have process hardening.

The 4000 series silicon alloy, also known as silicon aluminum.

The 5000 series magnesium alloy can solve the process hardening, the strength is comparable to the steel.

The 6000 series magnesium-silicon alloy is easy to process, can be deposited and hardened, and the strength

 is not very high.

The 7000 series zinc alloy can be precipitated and hardened, with the highest strength in all aluminum alloys.

8000 series mixing

The alloy element content of forging.
