How to melt molybdenum-copper alloy?
Molybdenum-copper alloy is an important industrial material. It has excellent thermal conductivity, corrosion resistance and mechanical properties, so it is widely used in aerospace, electronics, chemical industry and other fields. Melting is a crucial part of the preparation process of molybdenum-copper alloy. Let's introduce the smelting method of molybdenum-copper alloy.

First of all, the melting points of molybdenum and copper are 2623°C and 1083°C respectively, which are high melting point metals. Therefore, high temperature smelting technology is required to melt molybdenum-copper alloy. Arc melting method or vacuum melting method is usually used.

Arc melting method is to mix molybdenum and copper powders together through the high temperature of the arc, add appropriate amount of flux and regulating elements, and then melt the mixture into alloy liquid through the high temperature of the arc. Arc melting can use DC arc or AC arc, and the composition and quality of molybdenum-copper alloy can be ensured by controlling the temperature and stability of the arc.

The vacuum melting method is to put the pre-proportioned molybdenum and copper blocks into a vacuum melting furnace, and then evacuate the air in the furnace cavity through a vacuum pump, and then melt the alloy block into liquid through electric heating or electron beam heating. The vacuum melting method can prevent the alloy from being oxidized by air and producing impurities, so a higher purity molybdenum-copper alloy can be obtained.

During the smelting process, the composition control and temperature control of the alloy also need to be considered. By reasonably controlling the heating temperature and holding time, the uniformity and consistency of the alloy composition can be ensured. In addition, it is necessary to add an appropriate amount of flux and regulating elements to improve the fluidity and mechanical properties of the alloy.

In general, the smelting of molybdenum-copper alloy is a complex process, which requires strict control of the smelting temperature, time and process parameters to ensure that the composition and quality of the alloy meet the requirements. Only through strict smelting process and quality control can high-quality molybdenum-copper alloy products be produced to meet the needs of different industrial fields.
