For jewelry casting, manufacturers have a wide range of base metals and alloys to select from for their pieces. Most common metals that consumers are familiar with are gold, silver, platinum, and sterling silver. Yet there are many other types of alloys that may be used, including tin and zinc. When determining which alloy to…

Can Using Nickel Alloys for Jewelry Cause Problems?
When Baron Cronstedt originally extracted nickel in 1751, he intended to produce copper. That’s why he called this newly discovered metal kupfernickel, a German word that roughly translates in English to “devil’s copper.” Even though nickel’s a very useful and popular metal, the name might almost appear ironic to some people in modern times. Though…
Why Companies Are Switching from Lead to Bismuth for Copper and Tin Alloys
Are you looking for an alternative to lead-based alloys? Many companies are moving away from lead and copper and tin alloys due to the regulations and toxicity associated with the heavy metal, and that often means choosing bismuth. The good news is that bismuth has a relatively low melting point, and it’s durable and malleable…
