What is Aluminum CNC Machining Service?

Aluminum is a commonly used metal for CNC machining because of its excellent physical properties, surface morphology, high machinability and high strength to weight ratio. Our Aluminum CNC machining service is designed to meet your strict requirements to provide you parts with complex geometry. Your design and requirements and converted into a digital CAD file that is fed to a computer numerically controlled (CNC) machine. The machining centers use CNC machine axis to quickly produce precision aluminum parts. Kaierwo Aluminum CNC Rapid Prototyping services will let you achieve immediate and successful parts in just a day.

Benefits of CNC Aluminum Parts

High strength but light weight

Aluminum's density is only about one-third that of steel, that’s why aluminum products lighter and save machining cost, Also after alloying and heat treating, its strength can be greatly increased to meet the mechanical strength requirements of a wide range of applications. This high strength-to-weight ratio is particularly important in the aerospace and automotive industries.

Corrosion Resistance, Low Temperatures Resistance

Aluminum forms an oxide layer when exposed to air, protecting the metal from corrosion and chemical attack. Aluminum has different corrosion resistance depending on the grade of the material, and the most commonly used in aluminum CNC machining is 6061, which is usually used for automotive parts, sporting goods, some aircraft parts, etc.

Aluminum material is resistant to low temperatures, compared with other metals, aluminum is easier to process at low temperatures.

Easy Machining

Aluminum is easier to work with than other metals, and it can be easily stamping, folding, and drilling to create a variety of precise and complex parts in a variety of shapes. Aluminum CNC machining uses less energy and produces parts faster than steel machining.

Variety Of Surface Treatments

Aluminum CNC parts with a variety of surface finishing, such as Anodized, ,Laser carving,plating, painting, etc. Aluminum alloy surface treatment have their unique advantages, and different surface treatment should be selected according to specific usage scenarios. Consider factors such as wear resistance, corrosion resistance, and decorative properties when selecting, in order to ultimately achieve the best treatment effect.

Why choose Aluminum for CNC Machining?

CNC aluminum parts are usually less expensive

because they can be machined within a short period compared to other metals like steel. They also do not need extra finishes. Small quantities of zinc, magnesium, copper and other materials are added for strength because the pure aluminum metal is usually soft. When exposed to the atmosphere, a thin protective layer is formed which makes it resistant to corrosion and reduces the chances of it catching rust on the surface. It is resistant to chemicals, easy machining capabilities, and also has a lot of strength compared to its weight.

Aluminum weighs about a third as much as steel.

It also conducts heat and electricity easily which makes it the perfect material for steel sinks. Aluminum reflects heat and light, is malleable and non-magnetic. Some companies specialize in the production of custom CNC aluminum parts. This is mostly because they are economical and lightweight. Aluminum CNC parts are usually less expensive because they can be machined within a short period compared to other materials like brass and steel. It does not also require new finishes.
