In the world of advanced manufacturing, tooling is everything. The ability to cut, shape, and form materials with accuracy and repeatability sets the standard for product quality across industries—from aerospace and automotive to energy and defense. At the heart of these processes lies a material known for its toughness and reliability: tungsten carbide.

California Nanotechnologies (Cal Nano), a leader in materials innovation and advanced manufacturing, provides cutting-edge tungsten carbide tooling solutions designed for today’s most demanding applications. By combining the inherent properties of tungsten carbide with Cal Nano’s expertise in advanced processing methods like Field Assisted Sintering Technology (FAST), the company is able to deliver tooling that meets the highest expectations of precision, performance, and durability.

What is Tungsten Carbide Tooling?

Tungsten carbide is a compound made of tungsten and carbon atoms, typically bonded with a cobalt matrix to add toughness. This combination results in a material with exceptional hardness—second only to diamond—and the ability to maintain its edge under extreme stress and high temperatures.

Tungsten carbide tooling refers to the cutting, drilling, forming, and wear-resistant tools manufactured from this material. These tools outperform traditional high-speed steel (HSS) tools, offering longer service life, faster cutting speeds, and improved product finishes.

Key advantages include:

• Extreme Hardness – Maintains sharp edges even under abrasive conditions.
• Heat Resistance – Operates at high temperatures without losing performance.
• Wear Resistance – Withstands prolonged contact with tough materials.
• Dimensional Accuracy – Maintains precision tolerances over long production runs.

When is Tungsten Carbide Tooling Used?

Tungsten carbide tooling is employed whenever longevity, accuracy, and durability are required in manufacturing. It is the go-to choice for:

1. Metal Machining

• Cutting and shaping steels, stainless steels, superalloys, and cast irons.
• CNC milling, turning, and drilling operations in aerospace, automotive, and industrial sectors.

2. Mining, Oil & Gas, and Construction

• Drill tips, tunneling equipment, and wear-resistant inserts.
• Tools exposed to extreme abrasion and impact in rugged environments.

3. Woodworking and Plastics

• Saw blades, router bits, and knives for high-volume production.
• Injection molds and dies for plastics and composites.

4. Forming and Stamping

• Punches and dies for shaping stainless steel, titanium, and other hard alloys.
• Powder compaction dies in industries like energy storage and advanced ceramics.

In essence, if a process demands high wear resistance, precision, and heat tolerance, tungsten carbide tooling is the answer.

The Role of California Nanotechnologies
