銅とは何か？万能金属の総合ガイド
What is Copper? Understanding the Basics Copper is a chemical element with the symbol Cu and atomic number 29. It is a soft, malleable, and ductile metal with a distinctive reddish-orange color. Copper is a member of the transition metals group and is known for its excellent electrical and thermal conductivity, as well as its resistance to corrosion. Copper is a naturally occurring element that is found in the Earth’s crust. It is often found in mineral deposits, such as chalcopyrite (CuFeS₂), bornite (Cu₅FeS₄), and malachite (Cu₂CO₃(OH)₂). These minerals are extracted through mining processes and then refined to produce pure copper. Some of the key physical properties of copper include: […]

Thermoplastic Rubber (TPR): A Comprehensive Guide to Properties, Applications, and Benefits
What is Thermoplastic Rubber (TPR)? Thermoplastic Rubber (TPR), also known as thermoplastic elastomer (TPE), is a versatile material that combines the properties of rubber and plastic. TPR is a copolymer, consisting of a thermoplastic component and an elastomeric component, which allows it to exhibit both the flexibility and softness of rubber and the moldability and recyclability of plastic. The development of TPR began in the 1960s, driven by the need for a material that could offer the desirable properties of rubber while overcoming its limitations, such as difficulty in processing and recycling. Since then, TPR has evolved into a widely used material across various industries, thanks to its unique combination […]

While both materials have their strengths and weaknesses, understanding the key differences between polycarbonate and ABS can help you make informed decisions when choosing the best material for your specific application. In this comprehensive article, we will delve into the properties, applications, and distinctions between polycarbonate and ABS plastics. By the end of this piece, you will have a clear understanding of which material is best suited for your needs, whether […]
Alloys: Definition, Composition, Types, Properties, and Applications
Introduction An alloy is a material made by combining two or more metallic elements, often to achieve specific properties that are superior to those of the individual components. The history of alloys dates back thousands of years, with ancient civilizations using bronze, an alloy of copper and tin, for tools and weapons. Today, alloys are essential materials in various industries, from aerospace and automotive to construction and electronics. Alloys are created by melting and mixing different metals together, resulting in a homogeneous mixture with unique characteristics. The properties of an alloy depend on its composition, which is determined by the type and proportion of the constituent elements. By carefully selecting […]
