Cole & Swallow

Cole & Swallow

In its present form Cole & Swallow is a young company, but we can trace its origins back to the first brass foundry in the UK. For well over 100 years Cole & Swallow have been a leading UK manufacturer of copper and copper alloy tube specialising in precision engineered products.  Our skilled manufacturing processes enable us to produce tube with extremely tight tolerances, meeting highly demanding customer requirements. As the only UK manufacturer of defence standard tube in 90-10 and 70-30 copper-nickel and copper, our commitment to producing the highest quality tube has led to Cole & Swallow becoming a valued supplier to a number of first tier military sub-contractors.

Since becoming part of the Amari Metals Group in 2009, Cole & Swallow has strengthened its operational excellence and commitment to quality through substantial investments in stock, plant and equipment securing a long-term and highly competitive future.

For our customers we are not only a tube and component manufacturer but also a development partner and supplier offering a full spectrum of products.
