Genel Bakış TZM Powder
TZM powder is a specialized material composed of a blend of titanium (Ti), zirconium (Zr), and molybdenum (Mo), designed for use in high-performance industrial and scientific applications. Known for its exceptional strength, thermal stability, and resistance to wear and oxidation, TZM powder is a go-to material in industries like aerospace, energy, electronics, and manufacturing.
What makes TZM stand out? It’s all about its unique blend of metals that synergistically combine to deliver enhanced performance. This article explores everything about TZM powder, from its composition and properties to its applications and specific models. We’ll also discuss suppliers, pricing, and tips for choosing the right model.
What is TZM Powder?
TZM stands for Titanium-Zirconium-Molybdenum, a molybdenum-based alloy that has been reinforced with small amounts of titanium and zirconium. This alloy exhibits impressive mechanical and thermal properties, making it ideal for demanding applications.
Key Features of TZM Powder
- High melting point (~2617°C for molybdenum).
- Excellent thermal conductivity and low thermal expansion.
- Resistance to corrosion, oxidation, and creep at high temperatures.
- Superior strength and toughness compared to pure molybdenum.
