6K Additive and ADDMAN Sign $10.8 Million Nickel 718 Powder Agreement
Written with artificial intelligence.

6K Additive has entered a 30-month agreement to supply Nickel 718 alloy powder to ADDMAN Engineering, valued between $8.1 million and $10.8 million. The deal includes a buy-back program for used powder, enhancing recycling efforts and supporting domestic supply chains.
Agreement Overview
Pennsylvania-based 6K Additive has finalized a 30-month contract with ADDMAN Engineering, a Florida-based additive manufacturing and machining company, to supply Nickel 718 alloy powder. The contract is valued at a minimum of $8.1 million and could reach up to $10.8 million.
Supply and Buy-Back Program
The agreement not only covers the supply of the powder but also incorporates dedicated stocking support for ADDMAN. Additionally, 6K Additive will buy back ADDMAN’s used powder for reprocessing. This initiative aims to reduce reliance on overseas supply chains and maintain material integrity, particularly in critical sectors like defense.
Benefits for ADDMAN
ADDMAN's CEO Joe Calmese emphasized that this partnership enhances their capability to produce high-performance components for aerospace, defense, and energy applications. The collaboration supports a more sustainable approach to powder lifecycle management and aids ADDMAN in meeting increasing production demands with domestically sourced materials.
Reprocessing with UniMelt
Under the buy-back terms, 6K Additive will utilize its UniMelt microwave plasma system to convert ADDMAN’s used powder into new, high-quality powder. This process not only creates a circular supply loop but also ensures the production of spherical powders that meet the rigorous standards of additive manufacturing.
Expanding the Model
6K Additive's approach of combining powder sales with a buy-back program has been successfully implemented in previous partnerships, such as with Siemens Energy. This model allows customers to benefit from a continuous supply of high-quality materials while promoting sustainability within the additive manufacturing industry.
