When the Edge Matters: Angular Tungsten Carbide Powder
In thermal spray coating, particle shape is everything. And for applications that demand the highest levels of abrasion and sliding wear resistance, angular tungsten carbide powder is the standard that serious coating engineers reach for.
At Lineage Metallurgical — a Tungco company operating out of Baytown, Texas — our angular tungsten carbide powder is produced through a sintering and crushing process that results in hard, irregular, multi-faceted particles. That geometry isn’t an accident. It’s the feature.
Why Angular Particle Geometry Outperforms in Wear Applications
When angular particles are applied through HVOF (High Velocity Oxygen Fuel) thermal spray, they interlock within the coating matrix in a way that rounded or spherical particles cannot replicate. The result is a coating with:
- Superior abrasion resistance — the jagged geometry resists sliding wear at the surface level
- High hardness — sintered WC-Co and WC-Co-Cr grades deliver exceptional hardness values
- Excellent coating density — angular particles pack tightly under high-velocity spray conditions
- Strong bonding — irregular surfaces create more mechanical interlocking within the matrix
- Low porosity — critical for aerospace and oil and gas coating specifications
These properties make angular tungsten carbide powder the preferred choice for coating engineers in aerospace, oil and gas, petrochemical, and heavy industrial manufacturing — wherever components face abrasion, erosion, fretting, or impingement wear.
Lineage Angular Tungsten Carbide Products
Lineage offers a full range of angular (sintered and crushed) tungsten carbide powder grades, including:
- WC-Co-Cr 86/10/4 (LA-3386) — the workhorse grade for HVOF; excellent corrosion and abrasion resistance
- WC-Co 80/20 (LA-3204-25) — higher cobalt content for improved toughness in impact applications
- WC-Co 83/17 (LA-3203-25) — balanced hardness and toughness for general HVOF applications
- WC-Co 88/12 — high WC content for maximum hardness in sliding wear environments
All products are available per 1 lb and can be custom blended to specification for larger orders.
Aerospace-Grade Quality, Verified
Every lot of Lineage powder is tested before shipment. Lineage Metallurgical is ISO 9001:2015 and AS9100D certified, with certification by an ANAB-accredited body (PRI). Our powders are approved by Boeing, Bombardier, and Goodrich — a quality standard that speaks for itself.
The team behind every shipment — Julian Gonzalez and his Baytown crew, Josh McKnight, and Jerome Harrison — brings decades of combined thermal spray expertise to every order we fulfill.
