Aluminum alloy TIG and MIG welding process analysis: technology comparison, operation points and industry applications
Challenges and Importance of Welding Aluminum Alloys Aluminum alloys are widely used in automotive, aerospace and shipbuilding applications due to their light weight, high strength and corrosion resistance. However, its high thermal conductivity, oxidizability and susceptibility to thermal cracking make the welding process a serious challenge. Take the battery tray of new energy vehicles as an example, the weld needs to be both high strength and airtight, which is difficult to meet the needs of traditional processes, and TIG and MIG welding technology provides an efficient solution for this. Aluminum alloy features: low density: the density of aluminum alloy is smaller than that of steel and copper, about 2.7 g/cm3, so aluminum alloy products are lighter than steel products of the same volume. High strength: Aluminum alloy has high strength and hardness, and its strength and hardness can be significantly improved after heat treatment. Good electrical conductivity: the electrical conductivity of aluminum alloy is better than pure copper and steel...

How many types of aluminum corrosion are there?
Types of Aluminum Corrosion 1. Atmospheric Corrosion The most common form of aluminum corrosion. Atmospheric corrosion of aluminum occurs due to exposure to natural elements. Because of its likelihood of occurring in most places, atmospheric corrosion accounts for the largest share of the total damage to aluminum caused by all types of corrosion combined in the world. Atmospheric corrosion can be categorized into three subcategories. They are dry, wet and moist, depending on the level of moisture in the service environment. Since moisture levels can vary greatly depending on your geographic location, certain areas will experience greater corrosion than others. Other environmental factors that affect the level of atmospheric corrosion are changes in wind direction, temperature and precipitation. The concentration and type of pollutants in the air and proximity to large bodies of water also play an important role. 2.Galvanic Coupling Corrosion When aluminum is physically or through...

A356 Aluminum Alloy Comprehensive Guide: Properties, Applications and FAQs
The most widely used material for modern automotive cast aluminum alloys is the American Society for Testing and Materials (ASTM) grade A356 alloy, which is equivalent to China's ZL101A, Japan's AC4CH, Germany's AlSi7Mg, France's A-S7G03, and Russia's Aл9-1. In addition to the A356 alloy, Germany uses AlSi9Mg, AlSi10Mg, AlSi11Mg, and France uses A-S11G and A-S12.5. France also uses A-S11G, A-S12.5 . These high Si alloys are not heat-treated, they have good liquid mobility, strong shrinkage capacity, good casting performance, casting defects. But the mechanical properties and machine process performance is not as good as A356 alloy. Chemical Composition Element Symbol Composition Range (Mass %, %) Remarks (Maximum Allowable or Other Requirements) Si6.5 - 7.5 Primary alloying element to improve fluidity Mg0.25 - 0.45 Enhanced strength and heat treatment response Fe ≤ 0.20 Impurity element, required...

What is the difference between aluminum extrusion vs aluminum die casting?
In the field of industrial manufacturing, aluminum has become the material of choice in the automotive, electronics, and construction industries due to its lightweight, corrosion-resistant, and high-strength characteristics. However, the core difference between the two processes of aluminum extrusion (Aluminum Extrusion) and aluminum die casting (Aluminum Die Casting) directly affects the production cost, structural accuracy and mass production efficiency. As a deep ploughing aluminum die casting field 20 years of technical experts, ningbo he Xin die casting factory through this paper analysis of the engineering logic of the two processes, and share how to through the precision die casting technology for customers to reduce costs and increase efficiency. Forming principle of the essence of the contrast (the fundamental difference between the way the material flow) aluminum extrusion process through up to 15000 tons of hydraulic pressure, forcing the ingot heated to 400-500 ℃ through the hole of the special mold, this continuous plastic deformation process similar to the "toothpaste squeeze"...
