Precision CNC Machining in Metal

Before we get to the milling, turning, and boring of your CNC machined part, Triple J makes sure we are starting with the very best possible raw material for your specifications. Whether your component is to be used underground, on the highway, in orbit, or at home, you can be sure that Triple J will provide the highest quality materials to meet your requirements on budget. 

There is a vast world of industrial metals out there, and Triple J can guide you to the right choice every time. We keep a limited stock of the more common metals and alloys on hand, from stainless steel, copper, brass, multiple steel alloys, and more. If the right stock for your job needs to be ordered, we can do that for you as well, and typically have it in hand in just a few days. Once the material has been received and our quality management team has confirmed that all specs are met, production can begin. 

Quality Metals Make Quality Parts

From pure metals to special alloys, Triple J handles them all with skill and finesse. Turning, Some of our most frequently used metals: 

Steel Alloys –Triple J manufactures parts out of multiple stainless steel alloys, such as 4140 and 4130. These low-alloys use carbon, chromium, molybdenum, and other metals. They offer extraordinary strength and fatigue resistance. Tough, durable, and strong, these alloys are among the most commonly used metals in manufacturing.

Aluminum –Too soft for machining on its own, aluminum has properties that make it extremely useful in combination with other metals. When mixed with elements like copper or magnesium, aluminum delivers strength without adding much weight. Aluminum alloys are essential to many aeronautical, automotive, and medical applications, among many others. 

Brass – Copper combined with zinc becomes brass. But brass can take on countless guises, depending on the amount of zinc and other added elements such as lead, magnesium, iron, or nickel. There are countless varieties of brass, each offering distinct properties that give it signature strengths and weaknesses. 

Copper – Low cost and easy to machine, copper is too malleable on its own to be of much use in manufacturing. Yet, its unique properties make copper indispensable for many industrial applications. It is also resistant to rust and has inherent antimicrobial and antiviral properties.

Stainless Steel – With over 150 types of stainless steel in existence, the two most commonly used by Triple J are Type 410 and Type 316. Type 410 is classified as Martensitic steel that resists corrosion and can be hardened at high heat for added strength. Type 316 is Austenitic and combines 18% chromium, 14% Nickel, and also contains Molybdenum for greatly enhanced corrosion resistance.

Special Alloys – Inconel and Monel are among the most difficult materials to machine, but they offer tremendous value in performance. These “super-alloys” were developed to withstand extreme temperatures and intense pressure while also resisting corrosion. 

While both metals perform well in extreme heat and show exceptional resistance to corrosive environments, Inconel offers superior tensile strength, and Monel has greater resistance to the corrosive effects of seawater and steam.
