Industry leading lead-free and tin-lead alloys that meet demanding process requirements.

ALPHA® solder metals offer the best value for wave and selective soldering performance – quality products at the lowest cost of ownership. And thanks to a global copy exact product policy, consistency of supply is assured.

• High purity.
• Excellent solderability.
• High reliability.
• Low oxides, low drossing.
• Solder bar, chunks, anodes, preforms and solid wires.
• Vaculoy alloy conditioning process.

Cookson Electronics has been manufacturing soldering alloys for over 125 years. Today, with eight manufacturing locations globally, Cookson is the largest supplier of solder alloys for the electronics assembly industry. Our ongoing commitment to research and development has enabled us to understand the complexities of alloy performance resulting in a product line that meets our customers’ most demanding lead-free and tin-lead wave soldering processes and is backed by dedicated customer technical support.

The ALPHA line of wave soldering alloys consists of proprietary, specially developed products under our SACX® brand and the more common SAC and Sn/Pb alloys and other alloys that require third party licensing.

The SACX Family of Alloys

Engineered for high performance on certain types of assemblies or in specific applications, all SACX alloys demonstrate excellent soldering performance, low dross generation and high mechanical reliability. All SACX alloys are manufactured using our proprietary Vaculoy conditioning process.

• SAC305-like performance on complex, dual sided assemblies
• Low copper dissolution
• Lower silver (.8%) means lower cost

• Perfect for standard assemblies
• Excellent wetting and drainage resulting in high yields
• Great Value

• Great for single sided or simple dual sided assemblies
• Low copper dissolution

• Designed for use in wave, rework or selective solder applications
• Low copper dissolution during long exposure times

• High-value, low-cost pad finish
• Low consumption, uniform, flat coverage

We also manufacture additional Pb-free alloys including the high-performing industry standard SAC305, along with, SAC405, SAC387, SAC380, SA2515, and others. Each Pb-free alloy is also available in a copper-free version (i.e., SAC300) for solder pot replenishment and rebalancing.

• Sales and Engineering Support in every major electronics geographic market
• Continuity of supply ensured through multiple manufacturing sites
• Solder scrap value recovery
