When you pick a mandrel bending machine, you want it to work with many metals and pipe shapes. This means you can use one machine for lots of jobs. You can trust mandrel bending to make good bends, no matter the metal or shape.
Supported Metals
Mandrel bending works with many metals. You can bend steel, stainless steel, aluminum, copper, titanium, and galvanized pipes. Each metal is different. Aluminum is light and does not rust, so it is good for parts that need to be strong and easy to move. Stainless steel is tough and does not rust, so it works well in rough places. Copper bends easily and carries electricity, so it is used in plumbing and wires. Titanium is very strong and light, but it needs special care when bending. Mandrel bending machines use a mandrel inside the pipe. This stops the pipe from getting flat or wrinkled. The mandrel helps you make good bends, even with hard metals.
| Metal Type | Common Grades/Examples | Key Properties Relevant to Mandrel Bending | Industrial Applications/Notes |
| Mild Steel | Low-carbon steel (0.04-0.3% C) | Malleable, ductile, easier to bend | General bending applications |
| Spring Steel | High-carbon steel (up to 1% C) | Brittle, requires heating before bending, high yield strength | Springs, high-strength wires |
| Alloy Steel | AISI 1018, 4140 | Some require heat treatment, good strength | Lifting hooks, grab bars, U-bolts |
| Stainless Steel | 300-series (notably 304) | Ductile, corrosion resistant, cold bendable | Food, water, large diameter pipes |
| Aluminum | 6061, 3003, 5052 | Lightweight, corrosion-resistant, some grades bend better | Transportation, storage tanks |
| Copper | N/A | Highly malleable, durable, corrosion resistant | Bus bars, piping, railings |
| Brass | Alloy of copper and zinc | Malleability decreases with higher zinc | Simple bending processes |
| Bronze | Alloy of copper and tin | Less ductile, brittle | Limited bending applications |
Mandrel bending lets you use all these metals. You get strong and smooth bends every time.
Pipe Shapes
Mandrel pipe bending is not just for round pipes. You can also bend square, rectangular, and oval pipes. Some machines, like the Primapress 38CNC-5A-3S, let you bend bars, profiles, and wires too. This means you can do many jobs, like car exhausts or medical tubes. The mandrel inside keeps the pipe smooth and round, even with tight bends. You do not have to worry about the pipe losing its shape.
- Mandrel bending works with many pipe shapes and sizes.

Mandrel pipe bending lets you do many kinds of projects. You can help different industries without changing machines. This saves you time and money, and helps you give your customers great results.
Mandrel Bending Machine Capacity
When you choose a mandrel bending machine, you want to know what sizes and shapes it can handle. The right capacity lets you make complex parts with tight bends and smooth finishes. Let’s look at the key points you need to check.
Diameter & Thickness
You can use mandrel bending for pipes up to 38mm in diameter and 2mm in wall thickness. This range covers most needs in industries like automotive, HVAC, and furniture. The mandrel inside the pipe supports the walls during bending. This support keeps the pipe round and smooth, even when you bend thin-walled tubes. You get high-quality bends without wrinkles or flattening.
The Primapress 38CNC-5A-3S mandrel bending machine gives you this full range. The “5A” means it has five axes, so you can control every movement—bending, feeding, rotating, and more. This control helps you make parts with many bends and angles. You can store programs for up to 48 bends, which makes your work faster and more accurate.
Bending Radius
Mandrel bending lets you make tight bends, sometimes as small as the pipe’s own diameter. The mandrel inside the tube stops it from wrinkling or breaking. This is very important for thin tubes or parts that need to fit in small spaces. You can bend pipes with a radius up to 250mm and angles up to 185°. This wide range means you can make both tight and wide curves.
Mandrel pipe bending is the best way to keep the tube’s shape and size during tight bends. You avoid defects like flattening or collapse, even with thin-walled pipes.
Here’s a quick look at what you get with modern mandrel bending:
| Parameter | Value/Range |
| Max Diameter | 38mm |
| Max Thickness | 2mm |
| Max Bending Radius | 250mm |
| Max Bending Angle | 185° |
| Bending Speed | 100° per second |
High-speed bending, like 100° per second, helps you finish jobs quickly. You save time and boost your production. Mandrel bending also lets you make complex parts with many bends and different radii. This is why industries like automotive, aerospace, and medical devices use mandrel pipe bending for their most demanding jobs.
