1 Bromalloy 152 The ultimate high-temperature, wear-resistant and corrosive-resistant material specifically engineered for the glass industry.

2 Bromalloy 152 High surface finish. Excellent edge retention. Outstanding wear resistance. Improved production and part longevity translates into increased profitability. That s what makes Bromalloy 152 the most sought-after material for the hot, harsh glass industry environment. Bromalloy s unique, patented properties make it the ideal substance where hot glass contact, edge retention and wear are limiting factors such as plungers, guide rings, baffles and neck ring inserts. Because of its dense structure, Bromalloy s highly polished surface makes it the preferred material for delicate perfume and toiletry molds, PET molds as well as metal injection molds. And, most significantly, Bromalloy does not leach into hot glass. In fact, Bromalloy outwears nickel- and cobalt-based alloys by 40% to 60%.

Bromalloy is a patented, proprietary Ferro-Chrome-Boron alloy. The chromium level provides high corrosion and oxidation resistance. The eutectic iron-chromium boride provides excellent wear resistance even at elevated temperatures. Bromalloy can be investment cast to close tolerances or machined from bar stocks. Bi-metal parts such as inserted neck rings can also be investment cast. To facilitate machining, Bromalloy is usually supplied normalized to a hardness of 3 Rc. Although a hardness of 45 Rc is recommended for most glass applications, Bromalloy can be hardened to a maximum of 5 Rc to suit any application.
