Aluminum alloy is the most commonly used CNC machining materials. It features good performance, easy machining, lightness, low cost and can be subject to many surface treatment process.
Aluminum alloy is favored by engineers of all industries and is often used in CNC machining.
The most commonly used material for CNC machining is aluminum alloy, featuring comprehensive performance easy machining and which can be subject to all kinds of surface treatment. CNC machining aluminum alloy can be used to mechanical equipment, sports equipment, aerospace, automobile, ship, communications, optical equipment, medical equipment, robots and other fields and it is one of the most popular machining materials.
6061 aluminum alloy is high quality aluminum alloy products after heat treatment and pre-drawing process, the strength of which can not be compared with 2 or 7, but the properties of Mg and Silicon alloy are numerous. It is of good machining performance, good welding property and plating, good anti-corrosion, high toughness and it will not be deformed after machining. The materials are dense, of no defects and can be easily polished, easy painting film, oxidation effect and other good features.
Main alloy elements are Mg and Si. It is of good machining property and weldability, extrusion property and plating, good anti-corrosion, toughness, easy polishing and painting film, good anodizing and is a typical extruding alloy. The aluminum alloy sections and good plasticity, good heat treatment strength, good welding performance and anodizing and gorgeous color on the surface and other advantages and is widely used in building sections, irrigation pipes and pipes, bars and sections for vehicles, bench, furniture, lift and fence.
7075 refers a commonly used alloy in aluminum alloy 7. The alloy featuring best strength in commonly seen aluminum alloy is 7075. It is commonly used in parts made by CNC machining, suitable for plane structure and high strength accessories. Aluminum alloy 7 includes Zinc and Mg elements. Zinc is the main alloy elements in the series, so the anti-corrosion property is good and when a small amount of Mg alloy is added, the material can reach high strength after heat treatment. Main purposes include aviation fixation device, truck, tower building, ship, pipe and other fields that building needs strength, such as plane parts, gears and axle, fuse parts, instrument and gear, missile parts jump-in valve parts, turbine key, plane, aerospace and national defense application.
Aluminum 2017 is a typical duralumin in aluminum-copper-magnesium. The composition is reasonable and the comprehensive performance is good. Many counties produce this alloy and is mostly used in duralumin. The features of the alloy is: high strength, heat resistance, can be used as working parts when the temperature is below 150°C. When the temperature is higher than 125℃, the strength of 2017 alloy is higher than 7075 alloy. The shaping property is good in heat state, annealing and new quenching state and the heat treatment strengthening effect is significant, but the heat treatment process requirements are high. The anti-corrosion is poor, but the pure Aluminum cladding can provide effective protection; when welding, the cracks will be easily produced, but welding and riveting can be achieved by special process. It is widely used in general mechanical parts, plane, ship, transportation and building structural parts, transportation tool structural parts, propeller member and other structural parts.
This is a high-strength duralumin, which can be strengthened through heat treatment. The shaping property under the state of quenching and just quenching state is middle and the spot welding is good. There tend to be intercrystalline cracks at the time of gas welding. The alloy is of good machninability after quenching and cold hardening and it becomes lower after annealing; poor anti-corrosion, it is usually subject to anodizing and painting method or adding of aluminum on surface to improve the corrosion ability. The purpose is mainly used for making all kinds of high-load parts and members (not including stamping parts and forgings), such as the framework parts, skin, bulkhead, rib, spar, rivet and other working parts when the temperature is below 150℃。
5052 aluminum alloy is Al-Mg alloy, which is widely used, especially in building industry and is one of the alloy featuring good prospect. Good anti-corrosion, welding, cold machining and is of middle strength. 5052 aluminum alloy’s main alloy elements is Mg, which is of good shaping machining performance, anti-corrosion, welding and middle strength, used for manufacturing oil tank of plane, oil pipe and sheet metal parts, meter, streetlight holder and rivet, hardware and electric appliance shell of vehicle and ship.
5083 Aluminum alloy is high Mg alloy, which is of good strength in alloy that can not be subject to heat treatment, good anti-corrosion and machinability. The surface is beautiful after anodizing. The arc welding performance is good. 5083 alloy is mainly Mg, which is of good anti-corrosion and weldable performance and is of middle strength. Good anti-corrosion performance can enable 5083 to be widely used in maritime purposes such as ship, and automobile, plane welding parts and metro, pressure vessel that needs to be subject to fireproof (such as liquid tanker, refrigerator car, reefer container), refrigeration equipment, television tower, drilling equipment, transport and communication facilities, missile parts and armor.

There are many products in the market that are made of aluminum alloy, with bright and beautiful surface. This is another advantage of aluminum alloy apart from easy CNC machining: there are many choices for surface treatment, such as anodizing, powder spraying, painting, plating, passivation, polishing, drawing, sand blast, silk-screen printing, laser carving, IEF, CD picture, etching, highlighting and epoxying. Whatever your personalized design, we are willing to provide customized service.
There are many products and materials for CNC machining and the aluminum parts are one of the mostly machined. When CNC machining is used for aluminum parts, if you want to ensure more stable machining dimensions, you have to pay attention to these aspects.
In addition, the aluminum parts should also pay attention to chip removal and the use amount of cutting liquid during machining. There are many factors influencing the machining stability of the aluminum parts, therefore, we should face this flexibly during machining and analyze specifically. Stable tool, reasonable machining process and tool and the technological level of the operator are elements influencing product quality.
