Among numerous metal component assembly solutions, only a few can meet all application needs at the lowest cost. When it is necessary to withstand mechanical loads and ensure high clamping force, durability, and reasonable assembly costs, screws used for metal assembly become the best solution.
Our screws have always been used in industries with the most demanding demands. Over the years, we have established strong partnerships with car manufacturers around the world, whose designers and engineers recognize our professional business knowledge and trust that our products can meet any application or installation requirements.
Moving towards material innovation
Today, the material selection of automotive components is increasingly influenced by lightweight, energy-saving, safety, sustainability, and economic benefits. Steel, aluminum, magnesium, and copper are the main metals used in automotive components, and their use in each specific application complies with the standards set by automotive manufacturers.
Steel is a low-cost material widely used in key parts of most vehicle structures due to its ability to absorb impact energy. In addition to the body and chassis, steel is also used for many other automotive components such as the engine, wheels, doors, or hood. Among all these applications, high-strength steel (HSS) faces competition from potential alternatives.
One of the methods to achieve lightweight requirements is to replace them with lightweight metal alloys (such as aluminum or magnesium) without affecting application performance.
Aluminum alloy has excellent performance in strength and formability, and can replace high-strength steel. Due to its low density, high energy absorption rate, and good strength, aluminum consumption in automotive applications has increased by over 80% in the past few years. Aluminum castings are used for powertrain, chassis applications, electronic enclosures, and instrument panels.
The use of magnesium in automotive applications is also increasing. It is 33% lighter than aluminum and 75% lighter than steel/cast iron. Compared with steel and aluminum, magnesium alloys have excellent properties: the ability to absorb energy, high strength, low density, high heat dissipation, vibration absorption, and high elastic modulus. The sustained trend of reducing vehicle weight is expected to drive the growth of the magnesium alloy market.
Magnesium alloy is used for various body parts, internal components, and frames of automobiles, such as oil pumps, electronic casings, radiator brackets, etc.
