What you need to know when purchasing spark-free tools?

Explosion-proof tools are also called spark-free tools. They are called spark-free tools because they do not produce sparks due to mutual collisions during continuous impact and impact. At present, explosion-proof tools are made of beryllium bronze alloy and aluminum bronze alloy. Products made of beryllium bronze and aluminum bronze alloy will not cause safety accidents due to sparks due to friction, impact, etc. during use. Explosion-proof tools are particularly suitable for use in flammable, explosive, highly magnetic and corrosive workplaces, such as military industry, chemical industry, petroleum, petrochemicals, mines, coal mines, electronics, gas extraction sites and other special places. Explosion-proof tools It brings stability to our social security and also brings safety and security to our daily production. Explosion-proof tools have different properties from other tools because we use aluminum bronze alloy and beryllium bronze alloy to process and produce products. Products made of these two materials can be explosion-proof after processing. Among them, beryllium bronze alloy products are both explosion-proof and anti-magnetic. This product is particularly suitable for use in places with more stringent requirements. The performance of explosion-proof tools is also reflected in its good tensile strength. The tensile strength of beryllium bronze It can reach more than 25 degrees, and the tensile strength of aluminum bronze material has reached more than 35 degrees. These two products of different strengths allow customers to choose different workplaces to use our explosion-proof tools.

Explosion-proof tools can be divided into two categories based on material:

1. Aluminum-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. 2. Beryllium-copper alloy (commonly known as beryllium bronze) explosion-proof tools. The specific material is high-purity electrolytic copper as a matrix with an appropriate amount of beryllium, nickel and other metals 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, which can reach above HRC30o. Beryllium bronze is non-magnetic and can be used in strong magnetic field environments. Explosion-proof tools can also be divided into two categories based on manufacturing processes:

1. Casting process: It is a traditional manufacturing process. It is an internationally common process technology for manufacturing explosion-proof tools in the 1980s. It is still used by most domestic non sparking tool manufacturers today. Advantages of casting process: simple process and low manufacturing cost. Disadvantages: Product density, hardness, tensile strength, and torque are low, and there are many pores and trachoma, resulting in a shorter service life of the product.

2. Forging process: The latest international manufacturing process is made by using a large press or punch machine and a high heat-resistant forming die for one-time forging. Advantages of the forging process: It can greatly increase the product density, hardness, tensile strength and torque, basically eliminate pores and trachoma, and make the mechanical performance and service life of the product about 1 times longer than that of the traditional casting process. Disadvantages: Large investment in product equipment and molds results in higher costs.
