Standard Formats: Available in 1kg bars, chunked, 2kg and 4kg feeder ingots, 56g blowpipe, 125g and 250g tinman sticks. Weights are nominal.
Custom SAC Solder Alloy FAQ
How can I request custom SAC alloy ratios for electronics manufacturing? +
Please reach out to a knowledgeable member of the DKL Metals team to discuss your tailored SAC alloy requirements. We welcome the opportunity to learn about your unique manufacturing challenges and objectives. Our metallurgical experts collaborate closely with your engineering team to develop customised solder alloy solutions that enhance your assembly line processes and final product quality.
Are custom lead-free SAC alloys compatible with existing wave soldering machines? +
Yes, custom SAC alloys are engineered to work with standard wave, selective, and dip soldering equipment. When adjusting silver or copper ratios, we match the liquidus temperature profile to your equipment capabilities. We also factor in copper leaching rates from your specific circuit boards, ensuring the custom chemistry stabilises your existing solder pot without requiring costly machinery overhauls.
How do trace elements affect custom SAC alloy thermal fatigue resistance? +
Modifying standard SAC formulations by introducing micro-alloyed dopants like Nickel (Ni) or Bismuth (Bi) alters the crystalline grain structure. This tailoring directly boosts mechanical strength and minimises dross formation under high thermal stress. Our in-house laboratory services test these unique configurations to guarantee compliance with harsh-environment electronic assembly standards.
