(W, Ta) C powder products details

(W, Ta) C tungsten tantalum multiple carbide solid solution powder, the formula: (W Ta) C, gray-black powder, is a composite powder solidified by tungsten carbide and tantalum carbide, The tungsten tantalum carbide solid solution exhibits stable chemical composition, uniform distribution, high solid solubility, less impurities, uniform particle size, we can produce according to the specific requirements.


(W, Ta) C tungsten tantalum multiple carbide solid solution powder Advantages:
1. Raw materials with high purity: High purity tungsten oxide, tantalum oxide and high purity carbon black as raw materials,  to ensure the high purity of (W, Ta) C solid solution powder.

2. Special and patent additives: Patented additives ensure the grain size densification, uniform carbonization sintering,  uniform particle size;
3. Special carbonization sintering technology: Unique carbonization sintering technology to ensure a single-phase solid solution, low oxygen content, low free carbon, stable product quality.

 

products application

(W, Ta) C tungsten tantalum multiple carbide solid solution powder, as an additive of cemented carbide and cermets, can improve the performance of cemented carbide. Also (W, Ta) C powder can be used in thermal spraying, plasma spraying, hard film, the electronics industry.

(W, Ta) C products applications

(W, Ta) C tungsten tantalum multiple carbide solid solution powder is an important compound carbide powder in manufacturing high performance cemented carbide in the field of metal cutting (such as automobile and machine tool manufacturing). Compared with Fe-based alloy, the adoption of (W, Ta) C tungsten tantalum multiple carbide solid solution powder can improve the high temperature resistance, red hardness and anti-oxidation diffusion ability of the cemented carbide. Compared with the single carbide powder, (W, Ta) C solid solution powder exhibits higher hardness, higher temperature resistance, and better wettability with cobalt powder.
