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.
Advantages:greatly improved the performance in product density,hardness,tensile strenth,torque,basically eliminate porosity,trachoma.The machanical properties of products service life than traditional casting process 1 times.
Disavantages: product equipments,mold development,resulting higher cost.
