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.

Non- sparking spanners


The material of non sparking tools: Al-Br(QAl11-4-4), Be-Cu(QBe2)


Be-Cu: the color is green lake,hardness is not less than HRC35,tensile strength δ b 105-120kgf/mm2;standard code GBEX ⅡC,suitable for hydrogen with concentration 21.0±2.0%.Beryllium copper alloy with anti-magnetic performance.


Al-Cu: the color is bluish yellow,hardness is not less than HRC25,tensile strength δ b 75-85/mm2;standard code GBEX ⅡB,suitable for ethylene with concentration 7.8±0.5%,GBEX ⅡA (propane 6.5±0.5%),Ⅰ(methane 6.5±0.5%)。


Non sparking tools of XIN DA are made of high strength copper alloy.This kind hand tools can effectively prevent burning and explosion accidents caused by friction and collision between tools and tools in the flammable and explosive workplace.The explosion-proof performance received the certificates according to the national standard GB10686-2003, with the function of high intensity and good toughness.


The products are widely used in petroleum,chemical industry,mining,gas,coal,oxygen-producing,pharmacy,smelting,powder,leather,airplane,marine engineering etc,suitable for warehouse that operate flammable and explosive products,electrolytic workshops,communication assembly workshops,and requires that the tools are not rusty,wear-resistant and anti-magnetic during the checking process.
