Common Raw Materials Used In Precision Machining


Last Updated on April 21, 2024 by Saira Farman

Many precision machined products are made through precision machinery processes. This process creates the exact parts needed as single pieces or machinery components. These types of parts are made accordingly to the higher accuracy level to fit the varying needs of the function and match the system or machine they are mounted on. Most raw materials are used to produce the final needed pieces in the precision machinery process. Following are some raw materials used for completing the precision machining processes.

Stainless Steel

Stainless steel is a famous raw material for precision machining due to its resistance and strength to corrosion. Amongst the benefits of stainless steel is that it is welded vacuum-tight. However, several types of stainless have several treatment options. Stainless steel is a versatile material that makes Midwest Precision Machining top-notched.


Brass is another economical alternative. Brass has several benefits, such as ease of machining, cleaner and smoother finish, non-sparking, and holds threads and tolerances. This material is ideal for intricate parts that need sophisticated features. It should not be used for vacuum application because of the tin and zinc in the material. With Brass, the cast parts are usually made.


Aluminum offers several benefits, such as being easy to machine, lightweight, non-magnetic, inexpensive, and corrosion resistant. Aluminum is becoming the preferred choice over steel since it is easy to clean and machine, making it more useful. However, if you want the best results, you must hire the best Midwest Precision Machining experts who can handle aluminum welding. Other than benefits, this material can be machined tight to the tolerances and plated with several materials, which makes it harder or more conductive as a cost-effective alternative to steel, copper, or stainless steel.


Known for its durability and strength. Steel is the most popular metal for all types of manufacturing products. Steel is graded and used for specific purposes. It is easy to weld than other common materials. Generally, steel precision machining is used in industrial, auto manufacturing, and gas and oil industries. Steel is more inclined towards corrosion without plating or heat treatment.


Titanium is a costly and useful material for Precision Machined Products. It is highly resistant to heat and corrosion and is an extremely durable-to-weight ratio of any other metal. It is lighter, biocompatible, and inert, making it the best for various uses, from medical tools to aviation. However, the drawback of this material is that it is difficult to machine and the higher price. To use precision machining on titanium, you must work with the best and most experienced precision machine service provider.


Copper is another highly costly raw material for precision machining. Copper offers several benefits, such as durability, versatility, electrical conductivity, and corrosion resistance. Copper does not hold the tolerances and aluminum; however, it is a better conductor of electricity and even more when plated.

Engineered Plastics

Engineered plastic has changed drastically over the last decade. For the use of semiconducting, it has replaced aluminum and quartz due to its enhanced properties. The use of engineered plastics is higher in medical tools due to their ability to self-lubrication and can be cleaned easily. Engineered plastics have been made to compete with several strengths of metals.

Basic Plastics

Plastic is the inexpensive, non-conductive, and non-metal raw material used for machining. Since plastics can be modified and inert to fit the varying properties, plastic machinery is used in various medical, industrial, electronics, and scientific industries. Plastic is famous due to its smooth injection molding and lower costs.

Using all these raw materials, many Precision Machined Products are made per the needs of varying systems and applications. Connect with us now to learn everything about precision machining and our precision machining capabilities.
