Which Metals Can Be Sintered ?

🛠️ Pure Metals
• Iron: The most widely used sintered metal, known for its low cost and ease of forming. It is commonly employed in manufacturing mechanical structural components, gears, bearings, and more. Subsequent processes like carburizing and quenching can further enhance hardness and wear resistance.
• Copper: Excellent electrical and thermal conductivity, commonly used in the production of electrical contacts, heat dissipation components, bushings, etc. It is often alloyed with tin, lead, and other elements to improve performance.
• Aluminum: low density, corrosion-resistant, suitable for lightweight components such as automotive radiators and aerospace parts. However, it has relatively high sintering difficulty, requiring precise control of sintering atmosphere and temperature.

🧪 Alloy class
• Iron based alloys: Adding elements such as carbon, nickel, chromium, and molybdenum to iron can improve hardness, toughness, and corrosion resistance, making them the preferred choice for manufacturing high-strength gears, wear-resistant bearings, and engine parts.
• Copper based alloys: Common ones include bronze (copper tin alloy) and brass (copper zinc alloy). Bronze bushings are a typical application with good anti friction and impact resistance.
• Hard alloy: sintered with tungsten carbide and titanium carbide as hard phases and cobalt as a binder, with extremely high hardness, used in extreme wear-resistant scenarios such as cutting tools, molds, and mining machinery parts.
• Nickel based alloys: They have strong resistance to high temperatures and corrosion, and are commonly used for high-temperature components in the aerospace and chemical industries, such as turbine blades and valve parts.

🦾 Special Function Category
• Magnetic alloys, such as iron nickel alloys and ferrites, are sintered into permanent magnets and used in motors, sensors, and electronic devices.
• Refractory metals: metals with extremely high melting points such as tungsten, molybdenum, tantalum, etc., can be sintered into high-temperature furnace components, electron emitting materials, etc. through powder metallurgy.
