The head of the explosion-proof square wrench product is a square head. The tail has an anti-slip design and is a hand tool that uses the principle of leverage to twist bolts, screws, nuts and other threaded openings or hole fasteners that hold bolts or nuts. There is a clamp handle on the head that can be used to twist the bolt or nut and hold the opening or hole of the bolt or nut by applying external force to the handle.
Specifications,,,,,,,,,,,,,,
The explosion-proof wrench can be made into three styles, square wrench, round wrench, anti-slip wrench
Product material Use beryllium bronze, aluminum bronze alloy
Copper alloy (commonly known as aluminum bronze) explosion-proof tools. The specific material is high-purity electrolytic copper as the base, adding appropriate amounts of aluminum, nickel, manganese, iron and other metals to form a copper-based alloy.
Copper alloy (commonly known as beryllium bronze) explosion-proof tools are made of high-purity electrolytic copper as a base and appropriate amounts of beryllium, nickel and other metals are added to form a copper-based alloy. Both materials have very good thermal and electrical conductivity. After heat treatment, the hardness and wear resistance of aluminum bronze are almost the same as those of beryllium bronze. However, the magnetism of aluminum bronze is slightly higher than that of beryllium bronze, but both belong to the micromagnetic range. Both aluminum bronze and beryllium bronze can be used in strong magnetic field environment.
1. Description of the characteristics of beryllium bronze explosion-proof tools
Beryllium bronze explosion-proof tool specimens are a combination of military materials and precious and rare metals. The surface of the tool is yellow after being made. It is an internationally recognized authoritative explosion-proof tool.
The hardness of the working surface is no less than that of tensile strength, high explosion-proof performance and long service life. All other technical indicators have reached the advanced level of similar products at home and abroad.
In a space where flammable gas hydrogen (concentration is below), operate in strict accordance with the instruction manual to ensure safety. Impact (collision), friction, and falling weight will not cause spark explosions.
Beryllium bronze explosion-proof tools have zero magnetism, so they are also called anti-magnetic tools and can be used in magnetic field environments.
2. Description of the Characteristics of Aluminum Bronze Explosion-Proof Tools
Aluminum bronze explosion-proof tool specimens are synthesized with precious and rare metals, and the surface of the tool becomes yellow after being made.
The hardness of the working surface is no less than that of the tensile strength, and other technical indicators have all reached the advanced level of similar products at home and abroad.
