Tungsten Alloy for Mechanical Counterweight

The mechanical counterweight is a weight used to increase its own weight to maintain balance. In addition to being produced from cast iron, it can also be made from tungsten alloy. Compared with cast iron weight blocks, tungsten-based alloys have higher overall performance, which is mainly manifested in their higher relative density, better corrosion resistance and better oxidation resistance. In this way, not only can the product achieve the goal of small size and high weight, but also can make the product have a longer service life and a wider range of applications.

Cast iron concept: It is a general term for alloys mainly composed of iron, carbon and silicon. The chemical composition is generally: C (2.5%-4.0%), Si (1.0%-3.0%), P (0.4%-1.5%), S (0.02%-2%). When the carbon content is high, the plasticity is poor, the structure is uneven, and the weldability is not good. According to the different production components, cast iron can be divided into gray cast iron, ductile cast iron and malleable cast iron. Among them, the performance of gray cast iron mainly depends on the performance of the matrix and the quantity, shape, size, and distribution of graphite; it has high strength, good toughness, plasticity and machinability; it has higher strength than gray cast iron and also has plastic toughness. Great improvement.

Although cast iron is often used as a mechanical counterweight, its application in many places is limited due to its low density, easy oxidation and corrosion. Therefore, in some special fields, manufacturers often use tungsten alloy as a mechanical counterweight.

Tungsten-based alloy has excellent characteristics such as high density, high hardness, high tensile strength, wear resistance, impact resistance, high temperature resistance, corrosion resistance, easy processing, radiation resistance and good creep resistance, and it is environmentally friendly and non-toxic. The technological process is: mixing→vacuum drying→press forming→pre-burning degreasing→processing and forming→vacuum sintering→quality inspection→rough product→follow-up processing (oil immersion, machining, heat treatment, electroplating, rolling, forging, etc.)→ Refined products → product out of warehouse.
