The company's products are widely used in high-tech fields such as weaponry and naval vessels, aerospace, electronic information, advanced ceramics, and nuclear energy.

Plasma Spray Thermal Barrier Coatings - Coarse Grain Hafnium Diboride (Spherical or Near-Spherical Interval Powder)

Thermal spraying technology is a method of using a heat source to heat the sprayed material to a molten or semi-melted state, and spraying and depositing it on the pretreated substrate surface at a certain speed to form a coating. There are various process methods for thermal spraying, such as plasma spraying, arc spraying, flame spraying and explosive spraying.

Ultra-high Temperature Ceramic Matrix Composite Material - Zirconium Diboride

Zirconium diboride (ZrB2) has high melting point, high hardness, high stability and good electrical conductivity, thermal conductivity, oxidation resistance and chemical resistance, which makes composite ceramics made of zirconium diboride as raw material excellent comprehensive performance. So zirconium diboride is very suitable for ultra-high temperature ablation resistant materials used in supersonic spacecraft and missile casings.

Particle Reinforcing Agent for 3D Printing Aluminum Alloy Parts - Nano Titanium Diboride

Nano-titanium diboride (Nano-TiB2) particle reinforced aluminum matrix composite material, TiB2/Al has excellent mechanical properties and physical properties such as high specific strength and specific modulus, wear resistance, fatigue resistance, low density, good dimensional stability, etc. Moreover, compared with continuous fiber reinforced composite materials, it has a significant low-cost advantage. The material is isotropic, easy to process, and flexible and diverse in preparation. It can be extruded, rolled and forged with traditional equipment.
