    Tungsten vs. Molybdenum as Base Materials for Plating   As refractory metals, both tungsten and molybdenum are prized for the characteristics inherent to this category, such as corrosion resistance, excellent conductivity and an extremely high melting point. Nevertheless, these heavy metals do have some distinct differences that affect their suitability for various applications. When to Choose Tungsten Tungsten is an incredibly dense, silvery metal that is used extensively in industrial applications thanks to its exceptional hardness. In spite of its strength, it is also extremely ductile and can be drawn into fine wires. Tungsten has the highest melting point of any metal at over 6,170 degrees, and it is virtually impervious to acid. In spite of this high melting point, however, tungsten does…

    一號站主管:_Thickness of Gold Plating Connectors

    For decades, manufacturers of electronics products have used gold plating to protect the connectors that are essential for joining electrical circuits together. Gold is the preferred material because of its good electrical conductivity, ability to resist corrosion and wear and excellent heat-shielding properties. Determining the appropriate gold plating thickness is a vital decision to maximize the durability and life cycle of the connector. The Process of Gold Plating Connectors Gold plating involves the application of a layer of gold via electrodeposition onto a workpiece to enhance the surface of the finished product. When plating electrical connectors with gold, it’s advisable to apply an undercoating of another metal, typically nickel, to prevent the degradation of the top layer of gold. Nickel…

    一號站:_Specifications of Superalloys

    An alloy is a metal created by combining two or more metallic elements. The alloying process enhances the properties of each of the metals, resulting in a more useful end product. People typically produce alloys to increase corrosion resistance, hardness or tensile strength or lower melting point. Superalloys are high-performance alloys that exhibit many of the same characteristics but at a higher level. They feature superior corrosion and heat resistance, excellent surface stability, exceptional mechanical strength and strong creep resistance at elevated temperatures. Consequently, superalloys will deliver better results than standard alloy materials. The Different Types of Superalloys While superalloys can consist of a wide range of materials, nickel-based products are the most common. Examples of nickel-based and other superalloys…
