About Alpha Metals
Alpha Metals Solder & Electronic Assembly MaterialsMacDermid Alpha
The Alpha brand traces back to 1872, when the business began as a metals smelter and refiner, long before electronic assembly existed as an industry. Over the following century and a half, that metallurgical foundation evolved into one of the global leaders in electronic assembly materials, now operating as MacDermid Alpha Electronics Solutions.
Alpha today sits alongside the Kester and Electrolube brands within the MacDermid Alpha portfolio, delivering soldering and circuit protection solutions backed by more than 160 locations worldwide and what the company describes as the industry's largest electronics-materials R&D capability. The Alpha product range itself is a full-line supplier covering solder paste, stencils, squeegee blades, stencil and PCB cleaners, solder and cored wire solder, soldering fluxes, SMD adhesives, and semiconductor packaging materials including spheres for BGA and chip-scale applications.
A related Alpha Assembly Solutions entity in Singapore, formerly Alpha Metals Singapore, was incorporated in 1996, while an Alpha operation in Korea was separately founded in 1984 as a solder and solder-compound manufacturing business — reflecting the brand's long international footprint in electronic assembly materials. ChatMRO helps electronics manufacturers and PCB assembly shops match alloy composition, flux type, and packaging format against the Alpha catalog, and our team supports RFQ submissions for prototype or production-volume orders.

Frequently asked questions
What's the difference between Alpha solder paste and cored wire solder?
Solder paste is a suspension of solder powder and flux used primarily in surface-mount reflow soldering processes, while cored wire solder has flux embedded in its center and is used for manual or wave soldering of through-hole and rework connections. Your assembly method (reflow versus hand soldering) determines which format you need.
Are Alpha soldering products lead-free or leaded?
Alpha's catalog includes both leaded and lead-free (RoHS-compliant) solder alloy options across its paste and wire product lines, since different industries and regions have different regulatory requirements. Confirm your compliance requirement (such as RoHS) when specifying an alloy.
What is Alpha's relationship to Kester and Electrolube?
Alpha, Kester, and Electrolube are sibling brands operating together under MacDermid Alpha Electronics Solutions, each contributing soldering and protection materials to a combined electronic assembly portfolio. This consolidation gives customers access to a broader range of compatible soldering and conformal coating products under one supplier relationship.
Does Alpha make materials for BGA and chip-scale packaging?
Yes — the product line includes semiconductor packaging materials and solder spheres specifically designed for ball grid array (BGA) and chip-scale package (CSP) applications. These require tighter sphere-size tolerances than standard solder products, so confirm your package specification when ordering.
How do I find the right Alpha solder product without an exact part number?
Describe the alloy composition, flux type, and format (paste, wire, or sphere) you need, and ChatMRO's AI will match it against the indexed Alpha catalog. This is especially useful for PCB assembly shops standardizing on a specific alloy across multiple product lines.
