Miniature Stainless Steel Tubing
Also known as hypodermic or needle tubing, this tubing has thin walls and is made to tight tolerances for use in precision applications. It is welded with a smoothed weld bead on the inside to reduce particle buildup. Tubing connects by welding. To cut this tubing, you can use abrasive cutoff wheels and deburring tools or electrolytic cutting tools (not included).
304 stainless steel has very good corrosion resistance.
316 stainless steel has excellent corrosion resistance.

Ultra-Strength Lightweight Carbon Fiber Round Tubes
Often used in place of aluminum for structural frames, machinery components, and robotics, these tubes are lighter in weight and almost as rigid. Carbon fiber is known for its use in the aerospace industry where a balance of weight and strength is vital. Thanks to these tubes being lightweight, they reduce wear and stress on motorized parts to extend the life of machinery.
Plain matte tubes have fibers that run in one direction, making them strong in the direction of the fibers. They resist bending across the fibers but will splinter and separate like string cheese when bent along the length of the fiber. Matte carbon fiber is ready to paint and won’t reflect light, making it ideal for photography applications.
