EX-proof combination wrench set, Non-sparking copper alloy safety tool

详情

 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.

We are manufacturers specializing in the production of explosion-proof tools, our main products include a variety of aluminum bronze and beryllium bronze hammer, axe, wrench, screwdriver, pliers, scissors, shovels, pry, chisels, listening needles, as well as a variety of other special tools. Our products meet international quality standards.
