HAl77-2 Aluminum Brass Standard GB/T 13808-1992

HAl77-2 Aluminum Brass

Material Name: Arsenic-Added Aluminum Brass Extruded Bar (10-75mm)

Grade: HAl77-2

Standard: GB/T 13808-1992

●HAl77-2 Characteristics and Application Range: HAl77-2 is a typical aluminum brass with high strength and hardness, good plasticity. It can be processed under cold or hot conditions, exhibits good corrosion resistance to seawater and saline water, and resists impact corrosion. However, it has a tendency for dezincification and corrosion cracking.
