cnc machining parts material 

how to choose cnc machining parts material

Key Factors to consider the kind of CNC machining material includePrice; Electrical conductivity; Machinability; Thermal resistance; 
Strength; Hardness; Weight; Weldability; Chemical resistance; Performance to low or high temperature

The tips to choose suitable CNC machining material:
• Metals yield can get higher machining tolerance compared plastics.
• Plastics are usually not as expensive as metals.
• CNC machined parts cost usually is higher than sheet metal parts 
• Materials that don’t need surface finishing, like stainless steel, cost less both for prototyping machining and small batch orders.

aluminum cnc machined parts
Aluminum is a widely accepted metal that is economical and easy to machine. Aluminum is a lightweight, non-magnetic, 
silver-colored metal that can be machined to most shape. Designers and engineers usually choose aluminum for CNC machining and CNC
milling parts. It makes sense for their excellent machinability. 

Aluminum advantage for CNC machining:
• Soft, light, high strength
• Workable, Malleable, machinable
• Durable, corrosion resistant
• Non-magnetic, fire-retardant
• Easy anodization
• Low temperature resistant
• Electrical conductivity
• Good weldability

Aluminum Machining Parts Applications
Aluminum CNC machining parts can be widely used at a lot of industry.
• Automotive parts
• Housing, brackets, and other components for aerospace need support high duty but require light weight itself
• Fixtures, calipers, and a variety of other parts for industrial equipment
• Enclosures, panels, consoles, knobs, housing, and other applications for consumer and computer electronics.

Common Aluminum Used
Aluminum 6061: This grade is one of the most common aluminium. It is usually be used for general purpose. It provide good weldability, 
good corrosion resistance, excellent workability and machinability, its mechanical properties makes it ideal for many others applications. 
Benefits for aluminum 6061 to make CNC machining parts: low cost, versatility, excellent corrosion resistance, and superior appearance
after anodizing.
Aluminum 7075: The most common application for aluminum is known as aircraft or aerospace aluminum. Aluminum 7075 have key 
element zinc, which makes it have very high strength even can catch the strength of many steels. Aluminum 7075 also has convenient 
combination of properties for many applications. 
Benefits for aluminum 7075 to make CNC machining parts: high strength, high hardness, light weight, good corrosion resistance, and
high heat tolerance.
Aluminum 6082 is famous for its outstanding corrosion resistance and high strength, makes it very suitable to use in stressed applications. 
it can replace 6061 in many cases. The disadvantage is that it is difficult to produce thin walls.

cnc machined stainless steel parts

Stainless Steel is a steel alloy which contains a minimum of 10% chromium. The additional chromium provides a pristine surface finish and
exceptional corrosion resistance not found in carbon steels. The metal has a very high tensile strength, and has high resistance to wear,
resulting in added product durability and part longevity. Stainless steel provides excellent machinability, outstanding uniformity, and is
corrosion and oxidation resistant, leading to longer product life and lower total cost of machined parts. Because of its advantageous physical
properties, stainless steel has proven to be one of the more popular industrial alloys for CNC machining projects. While the best and fastest
way to make Stainless Steel parts is CNC machining especially CNC milling with stainless steel reach far and wide.

Stainless Steel physical properties
• Excellent heat resistance
• Excellent low temperatures resistance
• Excellent impact resistance
• Usually do not need surface finishing
• Excellent wear and corrosion resistance
• Very high tensile strength
• Good formability and weldability
• Easy to clean

Stainless Steel CNC Machining Parts Applications
• Robotics
• Food and health industry
• Consumer electronics spheres
• Medical and lab instruments
• Aerospace and marine
• Vacuum and pressure vessels
• Automotive,
• Construction and transportation
• Mining.

Common Stainless Steel Used
We offer a variety of stainless steel options to suit any specifications or requirements. Most common grade we use is S304, S316, S303.
Stainless steel 304 is the most common stainless steel. It is wildly used because it easily formed in various shapes. It have excellent
machinable and weldable. 304L stainless steel is the low carbon version of stainless steel 304.
Stainless steel 316: 316 The second most used stainless steel after 304, it has superior corrosion resistance particularly in chloride
containing environments and good elevated temperature strength. The low carbon version 316L has even better corrosion resistance in
welded structures.
Grade 303 is the most readily machineable of all the austenitic grades of stainless steel. It is basically the machining modification of
stainless steel 304. This property is due to the higher sulphur presence into the chemical composition. The sulphur presence improves
the machinability, but slightly lower the corrosion resistance and the toughness compared to the one of stainless steel 304.

Stainless Steel CNC Machining Parts Surface Finishing:
Sand blasting, shot blasting, polishing, anodizing, oxidation, electrophoresis, chromate, powder coating and painting.
In most condition, stainless steel CNC machining parts do not need any surface finishing treatment.
