Overview

Exothermic gas is a safe, inexpensive furnace protective atmosphere which produces bright product when annealing non-ferrous metals and mild steel, sintering iron and non-ferrous metal parts, copper brazing low carbon steel components and silver brazing yellow brass parts without surface metal vapor loss.

Exothermic gas generators produce either a lean or rich atmosphere composition depending on the chosen air-to-gas ratio. Exothermic gas is used for the thermal treatment of metals as a protective gas, which can be generated in an exothermic gas generator through burning natural gas.

The lean and rich atmosphere have differernt effects.

We offer exothermic gas generators for the usage in industrial furnaces. Aojie is a famous manufacturer of all types of furnaces and has therefore much experience with design and adaption of gas generators. Our customers are strongly satisfied with our products.

Hard brazing

Brazing solder has a melting point of more than 450°C and high joint strength, The strength of hard brazing joints is high, some kinds of brazing solders can be used in high temperature. There are many kinds of solder for hard brazing, the most widely used solder based on aluminum, silver, copper, manganese and nickel. Aluminum base solder is often used for brazing aluminum products. Silver base copper filler metal is often used for brazing copper and iron parts.

About Aojie

Started in early 1990’s Xi’an Aojie designed and manufactured its first mesh-belt controlled atmosphere continuous brazing furnace. In the years that have followed, Xi’an Aojie has committed to independent research and development of advanced brazing furnaces and heat treat equipments. Nowadays, Aojie mesh-belt continuous controlled atmosphere brazing furnace has successfully replaced imported equipment due to its unique advantages. Aojie mesh-belt controlled atmosphere brazing furnaces are widely used for brazing parts of stainless steel, carbon steel, aluminum, brass and copper, etc. by the industries of automobile, aero-space & aviation, and household appliances, etc.

Xi’an Aojie is a full service supplier, beginning with initial technical services such as feasibility studies, facility analysis and planning, continuing through equipment manufacturing, system installation, furnace start-up and operator training.

Aojie is always untiringly seeking to provide dependable equipment and technical support for customers to manufacture high-quality and low-cost products.
