[0001] The utility model relates to the technical field of explosion-proof tools, in particular to a beryllium bronze alloy combined explosion-proof tool with high-strength steel as a matrix. Background Art

[0002] Explosion-proof tools are made of copper alloy. Due to the good thermal conductivity of copper and its almost carbon-free properties, the heat generated in a short period of time when the tool and the object rub or collide is absorbed and conducted. Another reason is that copper itself is relatively soft and has good yield during friction and collision, and it is not easy to produce tiny metal particles. Therefore, we can hardly see sparks, so explosion-proof tools are also called spark-free tools.

[0003] Existing explosion-proof tools are made of various copper alloys, among which beryllium bronze has higher strength, but the cost is relatively high.
