	Technical Information

J-IV is a high noble Type IV casting alloy with myriad uses. The alloy has a large hardness range, which means when J-IV is bench cooled, it's perfect for restorations that must endure a high level of stress such as implants, long-span bridges and partial dentures. When it's water-cooled, the alloy is ideal for single units. J-IV melts, casts, finishes and polishes with ease and accuracy. The palladium-free version of J-IV is called JIV-PF.
