PTJ has been making precision turned and milled brass components since the late 2008’s.Whether for free cutting brass, engraving, or high-tensile, PTJ Prototype’s custom brass welding and fabrication services include applications for aerospace and more industries.

Few materials are easier to machine than brass, so smart brass component buyers choose their brass parts supplier by using a simple decisive factor: who can I trust to deliver the machined brass products I need precisely when I want them?

Brass Machining Benefits

Brass machining parts have several key advantages compared to machining other materials. Brass turned parts and components are durable, cost-efficient, and even create a tighter seal for fittings. In addition, brass machining and turning parts have a high heat and corrosion resistance! More importantly, PTJ Prototype’s brass screw machine parts are easy to machine and join, and made to your specifications and standards!

Grades Of Brass We Can Work With

From brass bar stock to round bar to brass tube, we offer brass material in all shapes. Brass can be easily joined to itself and all other copper alloys by soft soldering and brazing. Fabrication of intricate brass work is much easier than some other metals and results in cleaner lines due to elimination of screws, rivets, and other connecting devices.

PTJ Prototype Shop has the experienced staff and a full service CNC machine shop in China to perform brass machining on many types of brass, including:
