What Tube Sizes Does Xometry Offer for Bending and Cutting?
Xometry offers tube bending and laser tube cutting services via the Xometry Instant Quoting Engine®. Simply upload a tube design to start your quote and get pricing and manufacturability feedback right away.
Tube Bending
Tube bending services through Xometry are for round tubes, and the information below outlines a comprehensive list of available alloys and sizes. Files uploaded near the standard size listed below will assume that standard size for fabrication. These quick design for manufacturing (DFM) tips will ensure your project will quickly quote and be made with ease:
- Minimum bendable tube diameter: .250"
- Maximum bendable tube diameter: 2.000"
- Minimum bendable tube wall thickness: .035"
- Maximum bendable tube wall thickness: .188"
- A single piece can support multiple tube bends. However, a consistent center line radius (CLR) across multiple bends is recommended.
- We recommend a bend radius to tube diameter ratio of 2:1 to 5:1, no greater than 6", using the center line radius (CLR).
- For tubes under one inch, bend distances should be at least 2X the outer diameter. Increase that distance for larger tube diameters; for one to two inches, we suggest at least 3X the distance and 4X between bends for tubes over two inches.
- Assume normal-to-surface cutting for cut features and end conditions.

Round Tube Stock
Xometry uses a variety of round tube stock for its on-demand manufacturing services. The information below separates the metals and sizes by their availability for tube bending and laser tube cutting.
Stainless Steel Round Stock
Stainless Steel Round Stock
Stainless 304 and 316 tubes can be bent and cut in a variety of geometries. 304 is typically a general purpose stainless steel and 316 has increased corrosion resistance.
Round Stainless Steel 304, Welded
Round Stainless Steel 304, Seamless
Round Stainless Steel 316, Welded
Round Stainless Steel 316, Seamless
Alloy Steel Round Stock
Alloy steel tube has no shortage of uses, whether for handlebars, exhaust manifolds, construction, agriculture, or automotive applications. A513-5 DOM tubing has the largest list of available sizes in the category.
Round Steel 4130, Seamless (Chromoly)
Round Steel A513 Type 5, DOM
DOM: Drawn Over Mandrel
Round Steel A513 Type 1, HREW
HREW: Hot Rolled Electric-Welded
Round Steel A513 Type 2, CREW
CREW: Cold Rolled Electric-Welded
Square and Rectangular Tubing
Square and rectangular tubes can make large, cost-effective structural components at scale. The flat faces make this ideal for mechanical assemblies. These materials are available for Xometry's laser tube cutting service only.
Stainless Steel Square and Rectangular Stock
Stainless square or rectangular tubes are used to fabricate strong and durable structures in a wide realm of industrial, processing, agricultural, and transportation applications.
Square Stainless Steel 304, Welded
Rectangle Stainless Steel 304, Welded
Square Stainless Steel 316, Welded
Rectangle Stainless Steel 316, Welded
Aluminum Square and Rectangular Stock
Aluminum 6061 square or rectangular tubes are regularly used in Xometry's laser tube cutting services to build lightweight structural components for framing, overhead fixtures, brackets, shelving, and more. The information below outlines the available stock sizes for aluminum square and rectangular tubes.
Square Aluminum 6061, Extruded
Rectangle Aluminum 6061, Extruded
Alloy Steel Square and Rectangular Stock
Alloy steel A513 and 4130 square or rectangular tubes are high-strength and robust options for demanding structural requirements. 4130 is also known as chromoly, and is formulated to have a superior strength-to-weight ratio. A513 tubing is used for shelving and automotive frames.
