What elements does molybdenum-copper alloy contain?
Molybdenum-copper alloy is an important alloy material, which is mainly composed of molybdenum and copper, and usually contains a small amount of other elements. The elemental composition of molybdenum-copper alloy often includes the following:

1. Molybdenum (Mo): Molybdenum is the main component of molybdenum-copper alloy, and its content is usually between 50% and 90%. Molybdenum has a high melting point and high corrosion resistance, and is an important alloying element.

2. Copper (Cu): Copper is another main component of molybdenum-copper alloy, and its content is usually between 10% and 50%. Copper has good electrical and thermal conductivity, and the alloy formed with molybdenum can have excellent mechanical properties.

3. Iron (Fe): Iron is a common impurity in molybdenum-copper alloys, and its content is usually low. The presence of iron has a certain effect on the performance of molybdenum-copper alloys, but the performance of molybdenum-copper alloys can be adjusted by controlling the iron content.

4. Nickel (Ni): Nickel is another common impurity in molybdenum-copper alloys, and its content is usually low. Nickel can improve the corrosion resistance and thermal stability of molybdenum-copper alloys.

5. Manganese (Mn): Manganese is a trace element in molybdenum-copper alloys, and its content is usually very low. Manganese has little effect on the performance of molybdenum-copper alloys, but it can improve the brazing performance of the alloy to a certain extent.

6. Silicon (Si): Silicon is a trace element in molybdenum-copper alloys, and its content is usually very low. Silicon has little effect on the performance of molybdenum-copper alloys, but it can improve the oxidation resistance of the alloy.

In summary, the elemental composition of molybdenum-copper alloys mainly includes molybdenum, copper and a small amount of other elements. The content and ratio of these elements have an important influence on the performance of molybdenum-copper alloys. By reasonably controlling the element content, molybdenum-copper alloy materials with excellent performance can be obtained.
