Description

Buy neodymium magnetic gear magnets from Huiqiang Magnets – One of the earliest neodymium magnets manufacturer in China since 1994. We supply custom magnets in many shapes, sizes, and grades of neodymium magnets and assemblies. We are happy to provide our best price for you. Please note that the product show above is one of our made products for our customer, all of our products are made according customer’s requirements, unlike orders for stock magnets, custom magnet orders require a minimum purchase amount (according the specific requirements), and take about 3-4 weeks to fulfill.

NdFeB is used to manufacture the most powerful magnets per unit volume that are commercially available today. It is used where a small size and maximum power are needed. Neodymium Magnets exert very high forces and can attract each other through unbelievably large distances making them very popular for a wide range of applications including motors, generators,scientific experiments, NMR, electric cars, packaging, security, lighting, display to name a few. They also have an immense and unbeatable resistance to being demagnetised, making them ideal for repulsion applications as well as attractive applications. The magnets are triple coated(NiCuNi) for maximum protection against corrosion. Standard manufacturing tolerance is +/- 0.1mm on all dimensions.
