1.What is a "non-sparking" tool?
"Non-sparking", "spark reduced", "spark-resistant" or "spark-proof" tools are names given to tools made of metals
such as brass, bronze, Monel metal (copper-nickel alloy), copper-aluminum alloys (aluminum bronze), or copper-beryllium alloys (beryllium bronze).
Commonly used hand tools are often manufactured of steel
alloys. Preferred "non-sparking" 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.Application field
These tools can avoid to rise sparking when tools strike,rub or collide with target
in explosive atmosphere or flammble vapours and wide used in hazardous
environment where flammable and combustible vapors liquids gas dusts are
present such as petroleum industry,chemical industry ,power generation ,
railroad ,and mining etc.
3.Production method
(1) casting
(2) forging
Solid forging die
Machinery forgings, including freedom of die forgings and precision forging
4?Surface preparation
electrostatic spraying (spray coating)
Essential color (rue colors )
Passivation treatment (passivating treatment)
5.material for non sparking safety tools
1. Beryllium bronze explosion-proof tools explosion-proof performance
(a) Standard code: GBEx II C
(b) Hardness: HRC*5 above
(c) Tensile strength: ******0 KGF/mm²
(d) Magnetic: 0
2. Aluminium bronze explosion-proof tools explosion-proof performance
(a) Standard code: GBEx II B
(b) Hardness: HRC*5 above
(c) Tensile strength: ****5 KGF/mm²
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 swit.
