Problems solved by technology

However, in the prior art, since the preparation of copper-based amorphous alloys uses metals such as high-purity copper, high-purity titanium, high-purity zirconium, and high-purity nickel as raw materials, the prepared copper-based amorphous alloys There is a defect of high manufacturing cost, which in turn makes the cost of products made of copper-based amorphous alloys high, thus greatly limiting the wide application of copper-based amorphous alloys, making it difficult to achieve commercialization

Abstract

The invention relates to the technical field of amorphous alloy and in particular relates to a low-valent copper-based alloy ingot, a preparation method of the ingot and low-valent copper-based amorphous alloy prepared from the ingot. The main raw material of the low-valent copper-based alloy ingot comprises one of phosphor bronze, general berylco alloy, 7030 copper-nickel alloy, 9010 copper-nickel alloy, gas-atomized Cu-Ni 97 / 3 powder, super-elastic nickel-titanium alloy or zirconium-copper alloy; the low-valent copper-based amorphous alloy is formed by performing pressure casting on the low-valent copper-based alloy ingot. The low-valent copper-based alloy ingot is prepared from the raw material instead of or partially instead of a high-purity raw material; as the cost of the selected raw material is much lower than that of the high-purity raw material, the manufacturing cost of the low-valent copper-based alloy ingot and the low-valent copper-based amorphous alloy is low, and the copper-based amorphous alloy can be widely applied and commercialized. The prepared low-valent copper-based alloy ingot and low-valent copper-based amorphous alloy are very good in corrosion resistance and mechanical property.

Description

technical field [0001] The invention relates to the technical field of amorphous alloys, in particular to a low-priced copper-based alloy ingot, a preparation method thereof, and a low-priced copper-based amorphous alloy prepared by using the same. Background technique [0002] Amorphous alloys have been widely used in the fields of electronics, machinery, and chemicals because of their excellent properties in terms of strength, hardness, toughness, wear resistance, corrosion resistance, soft magnetism, and superconductivity. Copper-based amorphous alloy is a kind of amorphous alloy. Copper-based amorphous alloys use copper as the main element, and are generally composed of titanium, zirconium, nickel and other elements. However, in the prior art, since the preparation of copper-based amorphous alloys uses metals such as high-purity copper, high-purity titanium, high-purity zirconium, and high-purity nickel as raw materials, the prepared copper-based amorphous alloys There...
