I am looking to source Alnico magnets with specific dimensions for a project we are working on. We need one type with a diameter of 6 mm and a length of 120 mm, as well as another type that measures 4 mm in length and also 120 mm long. It's important to ensure that the magnets maintain their magnetic properties and quality given their intended use in our applications. Could you please provide information on your available options? Additionally, I'd appreciate details regarding minimum order quantities, lead times, and pricing for these products. Any technical specifications or data sheets you could share would be helpful in making our selection. Looking forward to your prompt response as we aim to finalize our sourcing soon.
