1. Hastelloy:
- Composition: Mainly composed of nickel, molybdenum, chromium and other elements.
- Performance:
- Corrosion resistance: It has excellent corrosion resistance and can resist corrosive media such as strong acids, chlorides, fluorides, etc.
- High temperature resistance: It can maintain good mechanical properties and strength in high temperature environments.
- Mechanical properties: It has excellent strength, hardness and toughness, and is suitable for high stress environments.
- Application areas: It is widely used in applications under extreme conditions such as chemical processing, petroleum refining, high temperature equipment and aerospace.
- Price: It is usually high, depending on the specific brand and market conditions, generally between US$2,000 and US$4,000 per kilogram.
2. Tungsten alloy:
- Composition: It is mainly composed of tungsten and a small amount of other elements (such as copper, nickel, and iron).
- Performance:
- High temperature resistance: Tungsten alloy has an extremely high melting point and can maintain stable performance at extremely high temperatures.
- Density: Tungsten alloy has a high density and is usually used in applications that require high-density materials.
- Wear resistance: Very wear-resistant, suitable for high-wear environments.
- Application areas: Used to manufacture high-temperature, high-pressure, high-density components, such as nozzles in aerospace, shielding materials in the nuclear industry, and high-density counterweights.
- Price: Relatively expensive, but the specific price depends on market conditions and required ingredients, and is usually in the higher range.
Summary:
- Choose Hastelloy: If there is a strong corrosive medium in the application environment or high-temperature stability is required, Hastelloy is a better choice.
- Choose black gold: If extremely high wear resistance, density or use at extremely high temperatures is required, black gold may be more suitable.
