Fusible Alloys

Fusible alloy is a leading supplier of fusible alloys for a broad range of Tool & Die applications.AIM fusible alloys are low melting temperature alloys that contain bismuth, lead, tin, cadmium or indium.  fusible alloys are utilized in a broad variety of tool & die applications, including casting, tube bending, machining parts for soft metal dies, fixturing, anchoring parts, toggle dies and supporting castings and interrupted cuts.
These silvery white alloys expand only ~3.3% of their volume when changing from liquid to solid form, which makes these alloys ideal for many industrial applications.  Fusible alloys are rarely consumed in an operation and therefore can be remelted and used multiple times. 
These alloys are normally used in gravity casting but also can be used in other casting methods. 
 

易熔合金是广泛用于工具和模具应用的易熔合金的领先供应商.易熔合金是包含铋,铅,锡,镉或铟的低熔点合金。的易熔合金可广泛用于各种工具和模具应用中,包括铸造,弯管,用于软金属模具的机加工零件,固定,锚固零件,肘节模具以及支撑铸件和不连续切割。
从液体形式变为固体形式时,这些银白色合金的体积膨胀仅为〜3.3%,这使得这些合金非常适合许多工业应用。易熔合金很少在操作中消耗,因此可以重熔并多次使用。 
这些合金通常用于重力铸造,但也可以用于其他铸造方法。
