High-hardness metal additive

Abstract

The invention relates to the field of metal additives used for aluminum, in particular to a high-hardness metal additive. The high-hardness metal additive is high in hardness, not prone to loose and capable of reducing metal loss in the aluminum alloy production process and improving the quality of produced aluminum alloy. The high-hardness metal additive is formed by compacting, by weight, 75-95parts of chromium powder, 4-24 parts of manganese powder, 0.3 part of iron powder and 0.7 part of silica powder.

Description

technical field [0001] The invention relates to the field of metal additives for aluminum, in particular to a high-hardness metal additive.

AI Technical Summary

Problems solved by technology

In the production process of aluminum alloys, metal elements need to be added to improve the performance of aluminum alloy products, and the dissolution of alloying elements in molten aluminum is an important process of alloying. Alloying elements commonly used in aluminum alloys are: silicon, copper, magnesium, Manganese, nickel, zinc, chromium, titanium, etc. At present, the method of adding elements to the alloy is generally to directly add the required elements to the molten aluminum, but due to the different melting points of various metals, it is easy to cause metal loss in the production process , so it is generally used to add metal additives to the molten aluminum to change the metal elements in the aluminum alloy, but the existing metal additives have low hardness, are easy to loosen, and are easy to affect the amount of metal added, thereby easily affecting the produced aluminum. The quality of the alloy, so it is necessary to develop a metal additive that can improve the quality of the produced aluminum alloy
