What is oxygen free copper used for?

Oxygen-free copper is a type of pure copper alloy which are highly refined to less than 0.5% oxygen concentration. In this state, the alloys retain their metallic properties but are free of oxygen and all pure copper alloys in an unoxidized (oxygen-free) form. Pure copper is highly reactive with moisture, making it unusable as an…

What’s the oxygen free copper?

Oxygen-Free Copper, abbreviated as OFC, generally refers to Copper with a 99.995% purity. Theoretically, oxygen-free copper is pure copper without oxygen or any residue of deoxidizer, but in fact, it contains trace oxygen and some impurities. The standard explains the content of oxygen is not more than 0.003%, the total content of impurities is not…

How to control the surface carbon content of carburized steel?

The surface carbon content and its distribution gradient of carburized steel parts have an important effect on its properties. High or low surface carbon content or decarburization will affect the surface strengthening of carburizing steel parts. In general, the carburizing process including carburizing → furnace air cooling → mechanical processing → heating quenching → cleaning…

The materials for condenser tubing

Condensation is one of the pivotal parts of a turbine generator set. A condenser converts a gas or vapor into a liquid and quickly transfers heat out of the tube. Its performance directly affects the operation of the unit. Condenser works in a high-temperature environment which is essentially an exothermic process. As the main heat…
