High specific gravity alloy
The high specific gravity alloy is an alloy with tungsten as the matrix (about 90 to 98%) and nickel, iron, copper or other components added, and the specific gravity is generally 17.0 to 18.5. This alloy has good high temperature strength, creep resistance, thermal conductivity and electron emission properties. Tungsten has a large specificity. In addition to being used in large quantities for the manufacture of hard alloys and alloy additives, tungsten alloys are widely used in the electronics and optical power industries, and are also used in the aerospace, casting, weapons and other sectors to make rocket nozzles and die-casting molds. , Armour-piercing bullet cores, contacts, heating elements and heat shields, etc.

Zirconia Precision Ceramic Parts
Zirconia has high melting point and boiling point, high hardness, is an insulator at room temperature, and has excellent properties such as electrical conductivity at high temperature.
Zirconia ceramics are widely used in the field of structural ceramics because of their high toughness, high bending strength and high wear resistance, excellent thermal insulation performance, and thermal expansion coefficient close to steel. Mainly include: zirconia molds, shaft cores, optical fiber pins, optical fiber sleeves, wire drawing molds and cutting tools, wear-resistant knives, watch cases and straps, bracelets and pendants, ball bearings and other wear-resistant parts.
In terms of functional ceramics, its excellent high temperature resistance is used as induction heating tubes, refractory materials, and heating elements.
Characteristics: wear resistance, heat resistance, acid resistance, corrosion resistance
Hardness: HRA 92-93
Density: 6-6.5 g/cm3
Ceramic watches, ceramic ornaments, ceramic structural parts, ceramic mandrels, textile accessories, etc.
Silicon carbide, ferrite absorbing material
Absorbing material refers to a type of material that can absorb the electromagnetic wave energy projected on its surface. With the development of modern science and technology, the impact of electromagnetic radiation on the environment is increasing. Therefore, the treatment of electromagnetic pollution and the search for a material that can withstand and weaken electromagnetic wave radiation-absorbing materials, has become a major subject of materials science.
The company's silicon carbide, ferrite and other absorbing materials have excellent performance, and the products have been approved and adopted by authoritative units such as NJ Electronics Research Institute.
At present, the products have been exported to developed countries and regions such as the United States, Germany, Italy, and Japan.
