What is the use of germanium-copper alloy?

An alloy of germanium, manganese and copper. It is divided into two types: high germanium manganese copper alloy and low germanium manganese copper alloy. It has low temperature coefficient of resistance and good flexibility in the range of 0 ~ 70℃. Greatly expanded the use temperature range of precision resistors. It is widely used to make standard resistors, precision resistors and precision electronic balance sampling resistors. -Cu-Ge alloy is a Cu-Ge alloy with high germanium content, with germanium content of 9%-9.5%. M density 8.5g/cm? Melting point 925℃, tensile strength 392~44 1Mpa, elongation >: 30% Cu-Ge alloy is made of copper and germanium in a certain proportion, and then cast into ingots or made into granular pellets. The main purpose of editing this paragraph is that industrial germanium is most commonly used in semiconductors to make transistors. Germanium has good semiconductor properties, such as electron mobility and hole mobility, which can convert light energy into electric energy and generate electricity by using temperature difference. Germanium produced in modern industry mainly comes from the by-products of copper, lead and zinc smelting. Most applications of germanium appear in the form of germanium alloy, and copper-germanium alloy is one of them. Belonging to a novel civil material. Germanium can usually be combined with silicon, gold, titanium, copper and other synthetic alloy materials. The arrangement of atoms in germanium crystal is the same as that of diamond, so its physical properties are hard and brittle. Because it is fragile and easy to peel off, germanium, copper and silver are used to synthesize alloy materials in industry to solve various industrial uses of germanium.
