Problems solved by technology

Iron is a major harmful impurity in cast aluminum alloys. With the increase of iron content, needles and flaky brittle iron phases with high hardness will be formed in the metallographic structure. Its existence splits the aluminum alloy. The matrix reduces the mechanical properties of the alloy, especially the toughness, and increases the difficulty of machining parts, severe wear of knives and cutting tools, and poor dimensional stability

Abstract

The invention provides a formula of an aluminum alloy hub material. The material comprises the following ingredients by weight: 6.5-7.5% of Si, 0.3-0.4% of Cu, 0.4-0.6% of Mg, 0.3-0.4% of Mn, 0.02-0.04% of Ni, 0.2-0.4% of Ti, 0.02-0.04% of Sr, 0.2-0.4% of Re, 0.01-0.04% of Zr and the rest of Al. The novel formula can not only effectively improve the mechanical properties of aluminum alloy, but also greatly improve the processing performance of a product and ensure the mechanical performance of the product.

Description

technical field [0001] The invention relates to a wheel hub material formula, in particular to an aluminum alloy wheel hub material formula. Background technique [0002] At present, the domestic wheel aluminum alloy mainly adopts A356 alloy (domestic brand: ZL101A), and its chemical composition contains: Si7%; Mg0. 35%; Fe < 0. 2%; Cu < 0. 2%; Zn < 0. 1% . Due to the high iron content in low-quality aluminum alloy ingots, and with the reuse of alloy furnace materials and the use of iron crucibles, tools, and roofing parts in production, the iron content of alloys continues to increase. Iron is a major harmful impurity in cast aluminum alloys. With the increase of iron content, needles and flaky brittle iron phases with high hardness will be formed in the metallographic structure. Its existence splits the aluminum alloy. The matrix reduces the mechanical properties of the alloy, especially the toughness, and increases the difficulty of mechanical processing of pa...
