What is non spark tools?
The material of explosion-pring tools?oof tools is copper alloy. Because of its good thermal conductivity
and almost no carbon content, the heat generated in a short time is absorbed and transmitted when the
tools and objects are rubbed or impacted. Another reason is that the copper itself is relatively soft and
has good yielding property when rubbing and impacting, so it is not easy to produce tiny metal particles.
So we can hardly see sparks, so explosion-proof tools are also called sparkless tools.

[about us ]
We’re manufacturer , the main products of our company are as follow:
1. Non-sparking tools. Aluminum copper alloy, beryllium copper alloy.
Non sparking tools can avoid rise sparking when tools strike,rub,collide with target in explosive atmosphere or flamble vapours .they are widely used in petroleum industry ,chemical industry ,power generation,railroad,mining,etc.
2. Special steel tools. carbon steel
3. Non-magnetic tools. Titanium alloy or stainless steel. The non magnetic tool, in strong magnetic field will not be magnetized, in the high temperature 600 °C when will not deformation, also in low temperature-250 °C still can maintain the good toughness No pollution, no radiation is the top of the world is the only tool of environmental protection.
4. Measuring Tools. Cast iron plate
