Introduction
In modern manufacturing, selecting the ideal material is just as critical as the machining process itself. The right choice directly impacts the component’s structural integrity, thermal performance, manufacturing cost, and overall lifecycle under operational stress. At Hankook Precision Machining, we engineer parts across a diverse spectrum of materials. This guide breaks down the metallurgical properties and specific use-cases of the most common industrial metals and polymers to help your team make informed procurement decisions.


1. Aluminum Alloys: The Workhorse of Modern MachiningAluminum is favored for its remarkable machinability, allowing CNC tools to cut through it rapidly, reducing cycle times and lowering shop-floor costs.
Aluminum 6061-T6: This is the absolute standard for general engineering. It offers great weldability, high structural strength, and responds exceptionally well to post-processing treatments like hard-coat anodizing.
Aluminum 7075-T6: When 6061 isn't strong enough, we step up to 7075. Alloyed primarily with zinc, its strength is comparable to many steels, making it a staple in the defense and aerospace sectors where weight reduction cannot compromise safety.
