1), Materials Al-cu,Be-cu

2), Aluminiumcopper alloy explosionproof tool is synthesis of precious metals, smelting, forging and tool made of the surface yellow. Beryllium copper alloy explosionproof tool for this is a synthesis of military materials and precious metals, made of tool surface is also yellow.

3), Aluminium-copper alloy explosion-proof tool HRC over 25°. Beryllium copper alloy explosion proof tool HRC over 35 °.

4), Tensile strength of aluminiumcopper alloy over 7585kgf/mm.. Beryllium copper alloy tensile strength over 105-120kgf/mm.

5), Aluminiumcopper alloy in ethylene concentration of 7.8% of space, beryllium copper alloy in the hydrogen concentration of 21% of space to ensure safety.

6), Aluminium-copper alloys are more applicable to conditions of pressure equipment and explosion-proof less stringent requirements on the environment (gas stations, small oil depots, etc.). Beryllium copper alloys for refineries to switch gas stations, gas production plants, drilling crew and so on.
