Electrical steel is the most important metal functional material for various electrical components. Oriented electrical steel is the core material for making iron cores of various oriented magnetic field electrical products such as transformers, ballasts, amplifiers, voltage regulators, relays, rectifiers, electromagnetic switches, etc. Utilizing the excellent magnetization properties of Goss-oriented

The surface and core materials of the substrate used in composite-based printed circuit boards are composed of different reinforcing materials. The mechanical properties and manufacturing costs of composite-based copper clad laminates are between paper-based copper clad laminates and epoxy glass fiber cloth copper-clad laminates. The composite-based copper clad laminate substrates

Explosive Bonding, Hot Bonding and Cold Bonding are three different metal bonding technologies, each with its own unique process principles, advantages and application scenarios. The following are the main differences between them: Clad Steel Process Principle Explosive Bonding Principle: Use the high-pressure shock wave generated by the explosion to press

20Cr2Ni4 is a low alloy carburizing steel widely used in the manufacture of mechanical parts that require high strength and wear resistance. This article will introduce the chemical composition, performance characteristics, main uses, and heat treatment process of 20Cr2Ni4 in detail to help readers fully understand this material. Carbon Steel

This question can be roughly divided into three situations to answer: First, the hardness HRC of mold steel LG with good toughness is between 50-58. The hardness of LG mold steel is HRC56-58, and its toughness is 8-9 times that of DC53. The ability of steel to resist fracture under

The Characteristics of The Welding Process of High Carbon steel Preheating and post-heat treatment: Preheating and post-heat treatment are usually required to reduce the tendency of welding cracks. Preheating temperature: Generally between 150°C and 350°C, depending on the type of steel and thickness. Post-heat treatment: Slow cooling after welding and

What Steel Is EM2? EM2 high-speed steel is a general-purpose tool steel widely used in rolling mills and other fields. Its chemical composition includes carbon, chromium, molybdenum, tungsten, vanadium, and other elements, and the content of these elements has an important influence on its performance. EM2 is a traditional Swedish

Powder steel powder metallurgy is a metallurgical method using metal powder as raw material. It is a special process that uses a certain amount of metal powder to synthesize, mix, sinter, and other processes to smelt a new type of metal material that can be used to manufacture tools and
