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.

Non Sparking Tools
We offer Non-Sparking Tools for application in explosive potential environments. All its tools are forged after casting to achieve the best quality tools in the market, both in mechanical properties and attractive finishing.We offer two kinds of material for its non sparking tools, copper beryllium alloy(Cu-Be) and Aluminium Bronze (Al-Br) alloy
Copper Beryllium Alloy	Composition		Be:			1.8% - 2%
			Ni:			0.2% - 0.5%
			Others:			<0.5%
			Rest:			Cu
	Hardness		35 - 40 HRC
	Tensile Strength		1250N/mm²
Aluminium Bronze Alloy	Composition		Al:		8% - 10%
			Ni:		2% - 5%
			Fe:		1.5% - 3%
			Others:		<0.5%
			Rest:		Cu
	Hardness		25 - 30HRC
	Tensile Strength		80N/mm²
Properties and Features	Among the features and properties of the alloy that our Non sparking tools offer are: Non Sparking 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
Use	The non-sparking tools are mainly 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. Rockwell hardness

Al-bronze   (HRC≥25°b>75-85kgf/mm²)

Be-bronze  (HRC≥35°b>105-120kgf/mm²)

4.Application field

In the normal process of using aluminum-copper alloys are more applicable to conditions of pressure equipment and explosion-proof environments with less stringent requirements (such as gas stations,small oil depots,etc.).The beryllium copper alloy explosion-proof tool for refineries to switch gas stations, gas production plants,drilling crew and so on.

5.The processing procedure

  Step1) To prepare the raw material, blanking

  Step2) Smelting

  Step3) Pouring

  Step4) Cut the water gap

Step5) Stored in the semi finished products warehouse

  Step6) Punching

  Step7) Through the drawbench or slotting machine

  Step8) PE plain end and chamfering

  Step9) Drill hole

  Step10) Perfect the product and marking

  Step11) If Be-bronze,need heat treatment

  Step12) Polishing

  Step13) Surface treatment
