Sintered metal is a versatile material used in a variety of applications due to its enhanced properties.
What is Sintered Metal Used For? 7 Key Applications Explained
1. Electrical Components and Semiconductors
Sintered metal is commonly used in the production of electrical components and semiconductors.
2. Optical Fibers
It is also used in the manufacturing of optical fibers.
3. Refractory Metals
Sintering is particularly useful for refractory metals like tungsten or molybdenum, which have high melting temperatures and cannot be easily melted.
4. Structural and Functional Parts
Sintered metal can be made from various types of metals and powders can be mixed to create unique alloys. Some common materials used for sintered parts include structural steel, porous metals for filtering, tungsten wiring, self-lubricating bearings, magnetic materials, electrical contacts, dental products, medical products, and cutting tools.
5. Metallurgical Applications
In metallurgical applications, sintering is used to manufacture gears, bearings, bushings, automotive parts, and structural components. Sintered metal components often exhibit higher strength, wear resistance, and dimensional accuracy compared to traditional cast parts.
6. Composite Materials
Sintering also plays a vital role in the production of composite materials. It is used to bond reinforcement materials, such as fibers or particles, with the matrix material in metal matrix composites (MMCs) and ceramic matrix composites (CMCs). This enhances the strength, stiffness, and toughness of the resulting composite material.
7. Polymers and Ceramics
In addition to metals, sintering is also used in the manufacturing of polymers and ceramics. Polymers are sintered for rapid prototyping, filter and silencer manufacture, and specialist composite components. Coarse metal powders are sintered to make filters, silencers, and oil-loaded bearings. Ceramics, including zirconia and alumina ceramics, are often sintered for the production of small parts such as gears and bearings for high-temperature use.
