Non sparking Adjustable Wrench Spanner, Copper Alloy Safety Hand Tools

详情

Commonly used hand tools are often manufactured of steel alloys. Preferred "nonsparking" metals have less tensile strength than steels usually used to make tools. A lower tensile strength means the metal has less strength or resistance to tearing apart when stretched under test conditions. It also means that these tools are softer, wear down more quickly than ordinary steel tools, and have to be dressed more frequently.

2.Explosion-proof tools technology parameters

3. Different application for different material

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 *5°. Beryllium copper alloy explosion proof tool HRC over *5 °.

4, Tensile strength of aluminiumcopper alloy over ***5kgf/mm.. Beryllium copper alloy tensile strength over ******0kgf/mm.

5, Aluminiumcopper alloy in ethylene concentration of 7.8% of space, beryllium copper alloy in the hydrogen concentration of *1% 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.
