A variety of look-alikes to SN100C are being promoted as fully compatible with existing baths of SN100C. Although the various names being used may look similar, all of these alloys contain additional alloying elements to the proven, patented SNCuNiGe mix, none of which have any long-term user or reliability data to support their claims, nor any pedigree user lists .
When SN100C was being developed, many other elements were looked at and rejected as having potential issues in long-term reliability and soldering uniformity. Offers by non-license holders to return failed baths to the original SN100C mix have no validity as existing international patents would be violated

About DKL Metals Ltd.
Established in 1986 as an independent manufacturer of tin/lead alloys, DKL Metals Ltd. has grown to become one of the UK’s leading suppliers of high purity solders and alloys — manufactured in accordance with national and international standards or customer proprietary specifications. It is DKL Metals’ policy to pursue the highest standards of quality and consistency to satisfy the varied and exacting demands of the modern manufacturing industry. In recognition of pending EU legislation to remove lead and other harmful materials under RoHS, DKL Metals formed a number of strategic alliances with like-minded independent companies and, in 2002, signed a manufacturing license with Nihon Superior Co. Ltd. of Japan to produce its SN100 range of lead-free solders. At this time they also formally linked up with Balver Zinn of Germany and a year later with FCTA, USA offering customers a global supply network of lead-free solutions.
