Tin’s sudden price surge has been driven by a collision of tight supply, aggressive investor activity, and rapidly expanding demand from modern technology sectors. Over the past few weeks, the metal has become one of the strongest performers in the industrial commodities market, including a dramatic 12.5% overnight jump that caught even seasoned analysts off guard. Much of this volatility stems from supply constraints in major producing regions such as Indonesia and Myanmar, where export r …

Rotometals' recently had the thrill of discovering our lead shot was used as ballast weight during the filming of a high‑intensity action sequence. And, as fans of the show, Landman, it was a moment that hit us right in the sweet spot where industry meets entertainment. When you watch a truck explode on screen, the kind of explosion - that lifts the chassis, sends panels spinning, and creates that perfect bloom of fire and debris - it’s easy to assume it’s all chaos. In reality, it&r …

Modern AI systems may feel like pure software, but the physical reality behind them is anything but. Every model training run, every cloud workload, and every streamed video depends on massive cooling systems working around the clock to keep servers alive. These cooling loops—circulating thousands of gallons of water through heat exchangers, manifolds, and high‑density racks—are the hidden infrastructure that makes the digital world possible. And inside those cooling systems, quietly …

Understanding strength, shine, detail, and casting performance across the four flagship alloys. Modern pewter casting has evolved far beyond its historical roots. Today’s makers — from jewelers and sculptors to hobby casters and small‑batch manufacturers — expect alloys that pour smoothly, capture fine detail, finish beautifully, and remain consistent from batch to batch. That’s exactly why so many creators rely on RotoMetals pewter. Our four primary alloys — R‑92, …

Bleigießen is a fascinating and lesser‑known New Year’s Eve tradition that has its roots in Central Europe, most prominently in Germany and Austria, where it became a beloved custom for families to gather together and melt small pieces of metal before pouring them into a bowl of cold water. The resulting shapes, often strange and abstract, were then held up to the light or cast against a wall to be interpreted as symbols of what the coming year might bring. A heart might mean love, a …

Every crabber knows that the excitement of Dungeness season or the anticipation of snow crab runs can be dampened by one persistent problem: corrosion. Saltwater is unforgiving, and without proper protection, crab pots and gear can deteriorate quickly, cutting into both profits and enjoyment. At RotoMetals, we’ve long supplied commercial and recreational fishermen with reliable solutions, and our Marine line of crab pot anodes has become a trusted way to keep gear in service season after s …

Among the many challenges faced by boat owners and marina operators, few are as persistent as the slow, invisible damage caused by corrosion. Saltwater and brackish environments are relentless, attacking steel, aluminum, and other metals used in boat lifts, piers, and dock structures. At RotoMetals, we understand that protecting these investments is not just about convenience, but about extending the life of critical infrastructure. That is why our Boat Lift Zincs, part of our Marine line of ano …

When it comes to zinc die casting, few alloy families have earned the reputation and versatility of Zamak. At RotoMetals, we supply a range of Zamak alloys that balance strength, durability, and castability, each tailored to specific applications. Choosing the right alloy is not just a matter of chemistry; it’s about understanding how subtle differences in composition translate into performance in the real world. Among the most widely used are Zamak 2, 3, 5, 8, and 12, each offering unique …

Antimony is a metalloid with a long history and a modern strategic edge. With the symbol Sb and atomic number 51, it is brittle, silvery‑gray, and known for forming alloys that dramatically alter the properties of base metals. Unlike copper or aluminum, antimony is rarely used in pure form. Instead, its strength lies in how it transforms other materials—hardening lead, enhancing flame resistance, and stabilizing compounds that protect lives and infrastructure. The most familiar application …

Germanium is a rare metalloid that has quietly risen from scientific curiosity to strategic necessity. With the symbol Ge and atomic number 32, it sits just below silicon on the periodic table, sharing many of its semiconductor traits but offering unique advantages. Hard, brittle, and silvery‑gray, germanium has a melting point of 1,726°F (938°C) and resists oxidation, making it durable in demanding environments. Its ability to act as both conductor and insulator depending on conditions …
