Non Sparking Tools Open End Wrench Copper Alloy Explosion Proof

Specifications

the explosion-proof double-ended wrench is a special tool designed for flammable and explosive places. Its core characteristics and technical points are as follows:
I. Core characteristics
Explosion-proof principle
Forged with copper-based alloy (beryllium bronze or aluminum bronze), no sparks are generated by impact and friction, eliminating the risk of explosion from the root27.
Berylium bronze material is also anti-magnetic and suitable for strong magnetic field environments (such as aerospace and medical equipment maintenance)

Non sparking tools is also called safety tools or explosion proof tools.There are two types of materials.

1,Aluminum bronze,Al-Cu,aluminum,nickel,manganese,iron and other metals were added to the high purity electrolytic copper as matrix to form copper-based alloy.

2,Beryllium copper,Be-Cu,the copper base alloy was forming by adding some metals such as beryllium,nickel.

the thermal and electrical conductivity of these two materials are very good,beryllium bronze is non-magnetic and can be used in strong magnetic fields.

Explosion proof tools can be divided in two catagories by manufacturing process.

1.Cast,is a kind of traditional technique,it is an international technology for manufacturing explosion proof tools in 1980s.

   Advantages of casting process: simple process,lower manufacturing cost.

   Disadvantages: product density,hardness,tensile strength,low torque,more pores and trachoma lead to shorter service life.

2.Forging,is a kind of international manufacturing technology.Products can be made one-time forging by large press or punch press with heat-resistant forming die.
