the plates we produce are denser, more uniform in size, and better
in flatness.
Features of tungsten carbide sheet:
1. The purity of the raw materials is more than 99.5%, the impurity
content is very small, and the physical properties of the board are
more stable;
2. Using spray drying technology, the materials are protected by
high-purity nitrogen under fully sealed conditions, which
effectively reduces the possibility of oxygenation during the
preparation of the mixture, and the purity is better, and the
materials are not easy to be dirty;
3. Uniform density of cemented carbide plates: it is pressed by a
300Mpa isostatic press, which effectively prevents the occurrence
of pressing defects, and the density of the plate blanks is more
uniform;
4. The compactness of the plate is excellent, and the strength and
hardness indicators are excellent: the ship low-pressure sintering
technology is used to effectively eliminate the pores in the plate
and the quality is more stable.
5. Cryogenic treatment technology is used to improve the internal
metallographic structure of the plate, and the internal stress can
also be greatly eliminated, avoiding the occurrence of cracks in
the cutting and forming process of the plate.
The main purpose:
Tungsten steel sheet has excellent hardness, high hardness, good
wear resistance, high elastic modulus, high compressive strength,
good chemical stability (acid, alkali, high temperature oxidation
resistance), low impact toughness, low expansion coefficient, The
characteristics of thermal conductivity and electrical conductivity
similar to those of iron and its alloys, due to the great
advantages of tungsten steel turning tools, have been quickly
promoted in the industry. In just 50 years, due to the use of
tungsten steel turning tools, the metal cutting speed has increased
two hundred times, from ten meters per minute to more than two
kilometers. The heat-resistant tungsten steel still maintains good
elasticity and mechanical strength, and is generally used for
thicker cutting, intermittent cutting and poor parts clamping.
After coating, the effect is better, and it can be processed to
various materials of HRC50°. Corresponding to general tungsten
steel, it has 1 to 2 times the service life and excellent impact
resistance.

Production process:
Pulverizing → formula according to application requirements → wet
milling → mixing → crushing → drying → sieving → adding forming
agent → re-drying → sieving to obtain a mixture → granulating →
pressing → forming → sintering → forming (blank) →Flaw
inspection→Packing→Warehousing.
Super long service life
The high hardness, high strength and other properties of cemented
carbide can be 50 to 100 times longer than ordinary alloys in use,
eliminating the time and labor cost of frequent product
replacement, which greatly improves Improve production efficiency
and save a lot of production costs for enterprises.
