HTB

HTB Titanium Diboride (TiB₂) is a premium PVD coating recognized for its exceptional hardness, low coefficient of friction, and distinctive silver-gray appearance. Engineered to enhance the performance and longevity of tools and components, HTB excels in applications involving non-ferrous materials such as aluminum, titanium, magnesium, and copper alloys, as well as graphite machining.

Applications

Industrial & Manufacturing

Forming tools for aluminum, copper, and magnesium alloys
Punches and dies used in stamping soft metals or no-lead brass
Wear plates and guide components in dry-running or sliding systems
Graphite machining tools requiring reduced edge buildup and dust adhesion

Aerospace & Automotive

Machining tools for high-silicon aluminum and titanium alloys
Precision fixtures and supports used with lightweight structural materials
Sealing or bearing surfaces that interact with reactive alloys under dry conditions

Electronics & Electrical

Precision tooling for copper, brass, and silver alloy contacts
Forming and trimming dies for conductive and soft metals
Heat sinks, housings, and assemblies where electrical insulation or cleanliness is important

Medical & Consumer Goods

Components requiring non-reactive, low-friction contact with titanium or aluminum
Form tools for lightweight, bio-compatible metals
Decorative parts requiring a hard, clean silver-toned finish with minimal wear

Core Benefits

Exceptional Hardness: With a microhardness of approximately 4000 HV, HTB provides outstanding wear resistance, significantly extending the lifespan of coated components.
Ultra-Low Coefficient of Friction: Ranging from 0.10 to 0.20, HTB minimizes friction, reducing heat generation and preventing material adhesion, which is particularly beneficial when machining sticky or gummy materials.
High Oxidation Resistance: Maintains integrity and performance at oxidation temperatures up to 850°C (1562°F), ensuring reliability in high-temperature machining operations.
Chemical Inertness: Exhibits minimal reactivity with non-ferrous metals, preventing built-up edge formation and facilitating smoother machining processes.

Why Choose HTB Coating?

HTB is purpose-built for non-ferrous materials where other coatings struggle. Its extremely low coefficient of friction and chemically inert surface make it the ideal choice for applications involving aluminum, titanium, copper, magnesium, and even graphite. While many coatings emphasize hardness or heat resistance in steel-cutting environments, HTB focuses on clean interaction with softer, more reactive materials—delivering a smoother cut, less edge buildup, and longer tool or part life.

What sets HTB apart is how effectively it prevents material transfer and galling in environments where adhesion is the primary failure mode. It’s not just for machining—HTB also excels on forming tools, mold components, electrical contacts, and precision parts where surface quality, conductivity, or cleanliness matter. If you’re working with non-ferrous alloys or composite materials and need a coating that won’t chemically interfere, HTB offers a sharp, silver-toned solution designed to stay clean, cool, and consistent.

Deposition Process

The HTB coating is applied using advanced Physical Vapor Deposition (PVD) technology. This process involves the evaporation of titanium diboride in a high-vacuum environment, resulting in a thin, dense, and adherent ceramic layer on the component’s surface. The PVD technique ensures uniform coverage, excellent adhesion, and minimal impact on the component’s dimensional tolerances, making it suitable for precision applications.
