Copper-nickel alloy is also known as cupronickel, is a copper alloy with nickel as the main element. It includes copper-nickel binary alloys and nickel-copper alloys containing other alloys such as manganese, iron, zinc and aluminum. The element copper and nickel can solubilize with each other. When the content of nickel exceeds 16%, the metal surface…
The development of power generation technology requires large capacity and high parameter thermal power units to be used in recent years, and now super (super) critical units have become the main models in the power industry. The boiler is one of the three main engines in a thermal power plant. It has the largest volume,…
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…
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…
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 square and rectangular steel pipes are the commonly used pipe types in mechanical and structural, transportation applications, How to calculate their weight is a problem often faced by steel pipe suppliers, which is related to quotation and transportation cost. Today, we will introduce how to calculate the theoretical weight of the square pipe and…
