Magnetic Tubes
Build or modify your own magnetic separation equipment with Alpha Magnetics' range of Magnetic Tubes.
Magnetic Tubes, sometimes known as Magnetic Cartridges or Magnetic Bars, can remove unwanted ferrous material and contamination from dry particle products, liquids or slurries. By mounting within your existing equipment, either individually or in multiple-row arrays, tubes can be a cost-effective do-it-yourself solution.
Tubes consist of magnets that are fully encapsulated within stainless steel tubing to create a strong magnetic field along the side of the tube to attract and retain ferrous material. Ends are fully seal welded and can be either plain or tapped for mounting.
We provide a variety of different styles and strengths designed to suit different applications or budgets using either Rare Earth (Neodymium) or Ferrite Ceramic magnetic material.
For standard applications the tubes are either 25mm or 25.4mm (1") diameter. When installed in a grate arrangement, the gaps between tubes should not be more than 25mm, unless there are multiple rows of tubes.
Construction uses type 304 or 316 stainless steel tubing. High temperature options are available. Other size tubes are possible e.g. 50mm dia.
For Fine Powders we offer special magnets with a Teardrop shaped profile.
For heavy duty applications and/or large or abrasive product, we also manufacture heavy duty tubes that are 38.1mm (1.5") square. These tubes should be mounted at 45 degrees to the direction of product flow and allow a wider spacing between tubes than standard round tubes.

Teardrop Rare Earth Magnetic Tubes 11,000 Gauss
- Teardrop profile for filtering Fine Powders.
- Helps prevent build-up of powder which can cause bridging & blockages.
- Powder flows down the sides of the tube instead of piling up on the top.
- Ferrous contaminants are captured and migrate to the underside of the magnet.
- 25mm wide x 36mm high & custom made to your length.
- Plain or Tapped ends with 1 or 2 holes for mounting.
- Contact us for a brochure with more information.
Rare Earth Magnetic Tubes 10,000 Gauss
High strength tubes custom made in any length up to 1 metre.
25.4mm diameter.
Plain ends or Tapped at one or both ends.
Rare Earth Magnetic Tubes 6,000 Gauss
More economical but still high strength tubes custom made in any length up to 1 metre.
25.4mm diameter. Durable 1.2mm wall thickness.
Plain ends or Tapped at one or both ends.
Ferrite Ceramic Magnetic Tubes
Standard strength tubes (approx. 2000 Gauss) for cost-effective solutions on a budget, custom made in any length up to 1 metre.
25.4mm diameter. Durable 1.2mm wall thickness.
Plain ends or Tapped at one or both ends.
Heavy Duty Rare Earth Square Magnetic Tubes
High strength tubes for large or abrasive products, custom made in any length up to 1 metre. Size: 38.1mm (1.5") square.
Very durable 1.6mm wall thickness 304 Stainless Steel.
These tubes should be mounted at 45 degrees to the direction of product flow and allow a wider spacing between tubes than standard round tubes.
5000+ Gauss on the surface but designed for the magnetism to reach out further than 25mm round tubes.
Heavy Duty Ferrite Ceramic Square Magnetic Tubes
Standard strength tubes for large or abrasive products, custom made in any length up to 1 metre. Size: 38.1mm (1.5") square.
Very durable 1.6mm wall thickness 304 Stainless Steel.
These tubes should be mounted at 45 degrees to the direction of product flow and allow a wider spacing between tubes than standard round tubes.
1500+ Gauss on the surface but designed for the magnetism to reach out further than 25mm round tubes.
Special Design Magnetic Tube
Special designs are available such as pointed ends or threaded ends with bosses.
Pointed ends make cleaning easier. Bosses give a more robust fixing method against a door or drawer front panel where the tube is fixed at one end only (like a probe or finger type magnet).
