●Main features and scope of application:

Industrial pure aluminum has the characteristics of high plasticity, corrosion resistance, good electrical conductivity and thermal conductivity, but low strength and impenetrable
Strengthened by heat treatment, poor machinability, acceptable contact welding, gas welding. Make more use of its advantages to make some tools
Structural parts with specific properties, such as gaskets and capacitors made of aluminum foil, electronic tube isolation nets, wires, cables
Protective cover, net, wire core and aircraft ventilation system parts and decorations; 1035 aluminum alloy is industrial pure aluminum,
Has high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but low strength, heat treatment can not strengthen the cut
Poor machinability; gas welding, hydrogen atom welding and contact welding, not easy to braze; easy to withstand various pressure processing and extension,
bending.

●Heat treatment process:

1) Rapid annealing: heating temperature is 350-410°C; depending on the effective thickness of the material, the holding time is between 30-120min; air or water cooling.
2) High-temperature annealing: heating temperature 350-500°C; when the thickness of the finished product is ≥6mm, the holding time is 10-30min;
3) Low temperature annealing: heating temperature 150-250°C; holding time 2-3h; air or water cooling
