This furnace is used for melting or heat-treating gold alloys, which combine gold with metals like silver, copper, or palladium to modify color and hardness. Operating at high temperatures (around 1100°C), it must provide clean, controlled heat. The working principle often involves induction melting for speed and homogeneity or crucible melting in a controlled atmosphere to prevent oxidation of the costly metal. Its purpose is in jewelry manufacturing, dental lab work, and coin minting to prepare specific karat gold alloys for casting or fabrication.

Trutherm manufactures 1400 Degree Celsius (°C) Gold Alloy Furnace 100 x 100 x 225 MM Chamber for buyers who search by exact machine type, chamber size and 1400°C temperature rating. This page is specific to the MM dimension version, so the chamber size is presented in the unit normally used in the buyer's drawing, tender or purchase request.
This configuration is suitable when the sample load must fit a 100 x 100 x 225 MM chamber with usable chamber volume of 2.4 litre, approximate power load of 4.1 kW, square chamber profile. It is commonly selected for laboratory, QC, metallurgical, ceramic, pharmaceutical and industrial heat-treatment work requiring stable heating and repeatable process conditions. Typical use includes general laboratory and industrial heat-treatment applications requiring stable, repeatable temperature control.
Where sample volume and process type vary week to week, a general-purpose muffle furnace avoids the cost of maintaining several process-specific furnace types.
A muffle furnace is usually the first furnace a lab installs, since it covers the broadest share of everyday heating, drying and ashing tasks before more specialised equipment is added.
As a general-purpose muffle furnace, this model covers a broader range of routine heating tasks than a process-specific ashing, tube or sintering furnace, making it the practical default when the lab runs mixed sample types rather than one dedicated process.
