UK-based Firth Rixson has signed a long term purchasing agreement with Pratt & Whitney Canada.

It continues the supply chain collaboration in place between the two companies since 2005. The cornerstone of the new agreement is the unprecedented term, extending to 2021.

Firth Rixson is a provider of engineered forged and speciality metal products.

The agreement provides price stability for both companies, and meets Pratt & Whitney’s long term sourcing initiatives. The UK company estimated the deal would lead to $1bn in sales over the term of the contract.
