Both tungsten carbide balls and steel balls can be used in bearings, hardware, electronics, iron art, electric power, mining, metallurgy, machinery and equipment, etc. However, the specifications of tungsten carbide balls or steel balls are selected according to the actual use. Below, let's take a look at the difference between these two kinds of balls.
(1) Different definitions
Tungsten carbide ball, English Tungsten Carbide Ball, chemical formula WC, is a black hexagonal crystal, and can also be called tungsten ball, pure tungsten ball, pure tungsten carbide ball or tungsten alloy ball.
Steel ball in English is steel ball. According to the different production and processing technology, it can be divided into grinding steel ball, forged steel ball, and cast steel ball; according to different processing materials, it can be divided into bearing steel ball, stainless steel ball, carbon steel ball, and copper bearing. Steel balls and so on.

(2) Different characteristics
Tungsten carbide ball has metallic luster, melting point is 2870℃, boiling point is 6000℃, relative density is 15.63 (18℃), insoluble in water, hydrochloric acid and sulfuric acid, but easily soluble in mixed acid of nitric acid and hydrofluoric acid, hardness and hardness Diamond is similar, with good electrical and thermal conductivity, excellent chemical stability, strong impact resistance, excellent wear resistance and other characteristics.
The rougher the surface of the steel ball, the smaller the effective contact area between the surface of the matching steel ball, the greater the pressure, and the faster the wear. The rough surface of the steel ball can easily cause corrosive gas or liquid to pass through the microscopic cracks on the surface, or the valleys on the surface of the steel ball can penetrate into the steel ball, causing corrosion on the surface of the steel ball.

(3) Different preparation methods
Tungsten carbide ball production method: on the basis of W-Ni-Fe tungsten alloy, add Co, Cr, Mo, B and RE (rare earth elements).
Steel ball production process: stamping → smooth grinding → quenching → hard grinding → appearance → fine grinding → cleaning → rust prevention → finished product packaging. Note: Automatic cleaning, appearance inspection (automatically reject unqualified products), automatic rust prevention and counting packaging are all key factors that affect the quality of steel balls.
(4) Different uses
Tungsten carbide balls can be used in armor-piercing bullets, hunting gear, shotguns, precision instruments, water meters, flow meters, ballpoint pens and other products.
Steel balls can be used in medical equipment, chemicals, aviation, aerospace, plastic hardware: perfume bottles, sprayers, valves, nail polish, motors, switches, electric irons, washing machines, refrigerators, air conditioners, medicinal materials, auto parts, bearings, instruments, baby bottles .
