MIM Material
Here is the good intro about the MIM
There are several materials that can be used for MIM (Metal Injection Molding) process, some of the most commonly used materials include:
- Stainless steel: This is a popular material choice for MIM due to its excellent corrosion resistance and strength.
- Titanium: This high-strength material is often used in aerospace and medical applications.
- Cobalt-chrome: This metal alloy has excellent wear and corrosion resistance, making it ideal for use in orthopedic implants.
- Inconel: This nickel-based alloy is known for its high-temperature strength and corrosion resistance, making it ideal for use in aerospace and gas turbine applications.
- Copper: This material has excellent electrical conductivity and thermal conductivity, making it a popular choice for electronic components.
- Tungsten: This high-density metal is often used in weights and counterweights, as well as for radiation shielding.
- Aluminum: This lightweight metal is often used in automotive and aerospace applications.
- Magnesium: This lightweight metal is known for its high strength-to-weight ratio, making it ideal for use in aerospace and automotive applications.
- Nickel: This material is often used for its high-temperature strength and corrosion resistance, as well as for its magnetic properties.
- Zirconium: This material is known for its excellent corrosion resistance and biocompatibility, making it ideal for use in medical implants.
