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.The processing procedure
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.The processing procedure
Al-bronze (HRC≥25°b>75-85kgf/mm² )
Be-bronze(HRC≥35°b>105-120kgf/mm²)
1) To prepare the raw material, blanking
2) Smelting
3) Pouring
4) Cut the water gap
5) Stored in the semi finished products warehouse
6) Punching
7) Through the drawbench or slotting machine
8) PE plain end and chamfering
9) Drill hole
10) Perfect the product and marking
11)If Be-bronze, need heat treatment
12) Polishing
13) Surface treatment
14)Stored in the finished products warehouse
3.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.
4.Production method
(1) casting
(2) forging
Solid forging die
Machinery forgings, including freedom of die forgings and precision forging
5．Surface preparation
electrostatic spraying (spray coating)
Essential color (rue colors )
Passivation treatment (passivating treatment)
