1.Beryllium bronze explosion-proof tools

Beryllium bronze is a universally recognized material for the manufacture of explosion-proof tools, using beryllium as the basic alloy. When beryllium bronze is subjected to high-speed impact or high-speed friction, its mechanical energy is converted into thermal energy when it is applied to the surface of the object, and the surface temperature suddenly rises. However, due to its high electrical conductivity and thermal conductivity, the heat on the work surface is quickly transferred to other parts of the workpiece, and the heat on the work surface is drastically reduced. The temperature of some particles detached from the workpiece under the impact or friction is also up to Less than the temperature of the ignition source. The compounds of beryllium bronze metals are relatively stable, have high melting points, and are not easy to violently oxidize. During high-speed impact or friction, although the temperature of the applied surface or some of the detached particles has risen, none of them can react violently with oxygen and other flammable gases, forming an ignition source. Beryllium copper alloy hand tools have antimagnetic properties in the presence of magnetic fields. Therefore, this material is the best material for making explosion-proof tools.

2, aluminum bronze explosion-proof tools

Aluminum bronze is a successfully developed aluminum bronze alloy material. In 1989, the aluminium bronze hand tools passed the inspection of the National Explosion-proof Product Testing Center and passed through domestic and foreign markets.

When aluminum bronze is subjected to high-speed impact or high-speed friction, its mechanical energy is converted into thermal energy when it is applied to the surface of the object, and the surface temperature suddenly rises. However, due to its high electrical conductivity and thermal conductivity, the heat on the work surface is quickly transferred to other parts of the workpiece, and the heat on the work surface is drastically reduced. The temperature of some particles detached from the workpiece under the impact or friction is also up to Less than the temperature of the ignition source. The compounds of aluminum bronze are relatively stable, have high melting points, and are not easy to violently oxidize. During high-speed impact or friction, although the temperature of the applied surface or some of the detached particles has risen, none of them can react violently with oxygen and other flammable gases, forming an ignition source. Therefore, this material is a high-quality material for making explosion-proof tools.

3. J892 explosion-proof tools

J892 copper alloy was successfully developed by Tianjin Explosion-proof Tools Research Institute in 1986: engineer Ding Jun and engineer Wu Yongxian and Baotou Explosion-proof Tool Factory (now Hebei Zhongbo Explosion-proof Tool Group Co., Ltd.) engineer Gao Xiangqi and Yang Dongjiang engineer successfully developed, its explosion-proof performance can replace Beryllium bronze explosion-proof tool products, J892 products have explosion-proof and anti-magnetic properties, recognized by the Spanish market, suitable for all types of explosive gas occasions. However, because the color of the product is similar to that of steel tools, the material is particularly expensive and has not been widely accepted by the market.

J892 explosion-proof tools are subject to high-speed impact or high-speed friction, when their mechanical energy is applied to the surface of the object is converted into thermal energy, the surface temperature suddenly rises. However, due to its high electrical conductivity and thermal conductivity, the heat on the work surface is quickly transferred to other parts of the workpiece, and the heat on the work surface is drastically reduced. The temperature of some particles detached from the workpiece under the impact or friction is also up to Less than the temperature of the ignition source. The compounds between J892 explosion-proof tools are relatively stable and have a high melting point, which is not easy to oxidize violently. During high-speed impact or friction, although the temperature of the applied surface or some of the detached particles has risen, none of them can react violently with oxygen and other flammable gases, forming an ignition source. Therefore, this material can be used to make explosion-proof and anti-magnetic tools.
