Characteristics of aluminum tubes and Scope


Aluminum tubes are applied earlier a heat-forged aluminum, better heat resistance, plasticity still in the hot state, it can be heat strengthened, corrosion resistance and weldability and machinability 2A70 close.Aluminum tubes chemical composition:

Si Si: 0.50-1.0

Iron Fe: 0.50-1.0

Copper Cu: 3.5-4.5

Manganese Mn: 0.20

Mg Mg: 0.40-0.8

Zinc Zn: 0.30

Titanium Ti: 0.15

Ni Ni: 1.8-2.3

Al Al: margin


Single: 0.05 Total: 0.10

Gravitational properties of aluminum tubing
