Raw Materials and Composition Analysis
When we talk about eco-friendly carbide manufacturing, the raw materials and their composition play a starring role. Traditional carbides are often made from tungsten carbide (WC) and cobalt (Co), but newer eco-friendly options focus on sustainable sourcing and alternatives.
- Recycled Tungsten Carbide: Extracted from old tools and components, reducing the need for virgin tungsten mining.
- Cobalt Alternatives: Exploring nickel or iron as binders to reduce reliance on cobalt, which is ethically and environmentally challenging to source.
- Nano-Scale Powders: Advanced powder technologies improve performance while using less material overall.
Specific Metal Powder Models
