How to Choose Suitable Materials for Your CNC Machining Parts
No matter what industry you are in, choosing the right material is one of the
most important factors in determining the overall function and cost of your
part.
CNC machining can manufacture precision machinery parts for almost any
application. This allows very tight tolerances for part dimensions and complex
designs. However, as with any manufacturing process, material selection such as
hardness, stiffness, chemical resistance, heat treatment, and thermal stability
are key factors in determining the overall function and cost of the project.
We manufacture machined CNC parts and prototype parts in a wide variety of
metal and plastic materials as well as other custom materials upon request.

Custom Metal CNC Machining Material

Soft metals such as aluminum and brass, as well as plastics, are generally
easier to machine and require less time to cut material from the workpiece,
reducing the time and cost of machining. Hard materials such as stainless steel
and carbon steel should be machined using slower spindle RPMs and machine feed
rates, resulting in longer machining times than softer materials. In general,
aluminum can be machined four times as fast as carbon steel, and stainless
steel can be machined half as fast as carbon steel.

The type of metal material is an important factor in determining the total cost
of a part. For example, a 6061 aluminum bar costs about half the cost of an
aluminum plate. The cost of 7075 aluminum rods can be two to three times the
cost of 6061 rods. 304 stainless steel costs about two to three times the cost
of 6061 aluminum and about twice the cost of 1018 carbon steel. Depending on
the size and shape of the part, material costs can be a significant portion of
the total price of the part. If your design does not require the performance of
carbon steel or stainless steel, consider 6061 aluminum to minimize material
costs.

Custom Plastic CNC Machining Material

If the product design does not require the rigidity of metal, plastic materials
can be a cheaper alternative to metal materials. Polyethylene is easy to
process and costs about 1/3 of 6061 aluminum. Plastics can be a cost-effective
alternative, but depending on the geometry, plastics may not be easy to meet
tight tolerances, and the stresses created when removing material can cause
parts to become brittle after machining and potentially warp.

Factors That Affect The Selecting of cheap cnc material
Application of Your Part
The end use of a CNC machined part has the greatest impact on material
selection. For example, if the part will be used outdoors or in a damp
environment, use stainless steel instead of carbon steel to prevent the part
from rusting. Design specifications such as stress loads, tolerances, and
fastener types (welds, rivets) also affect material selection. Specifications
such as military and aerospace components and the FDA regulatory environment
also influence material selection.

Does Part Weight Matter?
Generally speaking, if you want metal, a standard aluminum alloy like 6061 is a
good low density option to save weight. If the product does not require as much
strength, plastics such as ABS can help reduce weight even more.

Strength and Heat Resistance
There are many different ways to judge the strength of materials, such as
tensile strength, material hardness, wear resistance, etc. Selecting materials
of different strength types in conjunction with your design requirements can
help you determine the best material for a part. Additionally, very low or very
high temperatures can limit the use of certain materials. This is especially
true in environments with large temperature changes, as even small temperature
changes can cause some materials to expand or contract significantly.

The Budget of the Product
Manufacturability and overall cost of the project will affect your material
selection. Generally speaking, the more material you use in a part, the more it
will cost. Also, special and very strong materials such as titanium will cost
more.
