Product Overview

PRECISION POWDERS

Joint Carbide's carbide powder line covers two major categories -- Thermal Spray Powders and Cladding & Hardfacing Powders -- engineered for demanding surface protection applications across global industries.

Manufactured at our Ganzhou Jinshi Alloy Material facility with state-of-the-art spray drying, vacuum sintering densification and multi-instrument quality inspection, each powder batch delivers consistent particle morphology, flow rate and chemical purity.

Consistent Particle Morphology -- Spherical, free-flowing particles for uniform coating deposition.
Multi-Instrument QC -- Flow rate, granularity, carbon/sulfur, and rare metal content tested per batch.
Complete Grade Portfolio -- WC, WC-Ni, Cr₃C₂, TiC, TiC-CrFe and Nickel-based grades available.
Direct Manufacturer Pricing -- Backed by 19+ years of carbide material expertise and in-house raw material supply.
