The explosion-proof wrench (explosion-proof round head wrench with flower handle), also known as the explosion-proof wrench, is one of the explosion-proof tools produced by our company, which also includes explosion-proof methods. Head type wrench, explosion-proof anti-slip type wrench, explosion-proof wrench type crowbar, etc. Most products on the market are welded and cast, and the stressed parts are easy to break and bend, with poor strength and short service life. The tools produced by our company adopt a new production process and are forged in one go using a large friction press. It has high strength, good toughness, beautiful appearance and durability, replacing the welding and casting processes in the original market. Explosion-proof wrench, the head is a type wrench. The head is the working end, and it is a hand tool that uses the principle of leverage to twist bolts, screws, nuts and other thread-fastening openings or hole fasteners of bolts or nuts.
Made of aluminum bronze and beryllium bronze. Smelted from nickel-aluminum and nickel-beryllium alloys, beryllium bronze tools are national Class II products. They do not detonate gases when operating in high concentrations of hydrogen. Aluminum bronze tools are national Class II products and do not detonate gases when operating in high concentrations of ethylene gas.
Because beryllium bronze material has zero magnetism, beryllium bronze tools are also called anti-magnetic tools and can operate safely in magnetic field environments.
After stopping use, wipe it clean in time. If not used within half a year, it should be oiled or preserved with antiseptic method. If it is not used for more than one year, it should be oiled and stored in a bag or box.

Internationally, explosion-proof tools are collectively referred to as safety tools and non-sparking tools, and domestically, they are collectively referred to as explosion-proof tools.
The explosion-proof tools produced, sold and circulated in China can be divided into two categories according to their materials
Copper alloy (commonly known as aluminum bronze) explosion-proof tools, the specific material is high-purity electrolytic copper as the base with an appropriate amount of aluminum added , 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 are Can be used in strong magnetic field environments.
