1.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

2.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.
