Aluminum alloy material is favored by most engineers because it has low density, light weight, easy processing, and good surface treatment effect. It is suitable for various industries. 70% of the rapid prototype is aluminum alloy material. Each grade has a different state, hardness, strength, corrosion resistance, processability, weldability, and decorative properties. The selection should be based on the product's performance requirements, the use of the environment, processing and other factors. Molto Precise Machining Co.,LTD has stocks of these commonly used materials to ensure that customers can shorten the delivery time when they need to process rapid prototype and machined parts.
Low Density The density of aluminum is 2171 g/cm3, which is about one third of the steel density (7187 g/cm3).Hardness Many customers are very concerned about the hardness when ordering aluminum alloy machined parts and aluminum alloy hand model. The hardness has a direct relationship with the chemical composition and state of the alloy. The hardness of the aluminum alloy is ranked from high to low: 7 series, 2 series, 4 series, 6 series, 5 series, 3 series, 1 series.
Strength strength is an important factor that must be considered when designing a product. In particular, when an aluminum alloy component is used as a structural component, an appropriate alloy should be selected according to the pressure applied. The strength of pure aluminum is the lowest, and the strengths of heat-treated alloys of 2 and 7 series are the highest. There is a certain positive correlation between hardness and strength.
The Corrosion Resistance Corrosion resistance includes chemical resistance, electrochemical corrosion resistance, and stress corrosion resistance. In general, the corrosion resistance of 1 series pure aluminum is the best, 5 series is good, followed by 3 series and 6 series, 2 series and 7 series are poor, which can be judged, 1 series, 5 series, 3 series, 6 The anodizing effect is good, and the anodizing effect of the 2 and 7 series is poor.
Processing performance Aluminum alloy CNC machining, bending, stretching and other molding processability is very good, cutting performance and alloy composition have a great relationship, usually high strength aluminum alloy cutting performance is better.
Environmental protection Aluminum has a low melting point (660 °C) and is easy to recycle. Conducive to environmental protection and in line with sustainable development strategies.
