The working temperature range of vacuum aluminum brazing furnace varies depending on the model and purpose. The common maximum temperature can reach 750 ℃, and some high-temperature models can achieve temperatures of 1700 ℃ or higher. The following is a specific introduction:

Conventional model: A certain model of vacuum aluminum brazing furnace with an effective heating zone size of 600 × 200 × 2 × 500mm, with a maximum temperature of 750 ℃ and a maximum working temperature of 650 ℃; The VAB series is produced by Shenyang Best Vacuum Mechanical and Electrical Equipment Manufacturing Co., Ltd., with a working temperature of 700 ℃; The maximum temperature of WZLQH-30 vacuum aluminum brazing furnace is 800 ℃. The temperature range for aluminum brazing is generally between 595-615 ℃, and the uniformity of furnace temperature in the heating zone is very strict, generally not exceeding ± 3 ℃.

High temperature models: There are vacuum aluminum brazing furnaces that can meet the requirements of high temperature brazing, with a working temperature of up to 1700 ℃ (customizable according to needs), a maximum vacuum degree of 8 × 10 ⁻⁴ Pa, and furnace temperature uniformity of ± 5 ° C. There are also models with a maximum temperature of 1350 ℃ (as of April 2025); Shenyang Kejing will launch ultra-high temperature models with a working temperature of 2300 ℃ in 2025.
