Frequently Asked Questions...

What happens after I complete the form?

All information will be sent to our engineers to review. You’ll receive your quote within 1-3 business days (exception of national and some international holidays). Production will start once secure payment has been made.

How long will my order take to arrive?

We pride ourselves in having one of the fastest turnaround times in the industry, averaging 15 business days from payment.

What do Neodymium grades mean? (N35-N52)

The grades N35 to N52 refer to the maximum energy product, the higher the number the greater the magnetic field. Higher grades of Neodymium are generally more expensive, we find the N42 is the perfect balance between performance and cost.

What coating options are available?

We can offer most coating options. The most common coating for Neodymium magnets is Nickel and Cobalt (NiCuNi), but we also offer Zinc (Zn), Gold (Au), Rubber, Epoxy and Titanium (Ti), to name a few.

What if I have special requirements?

If you have requirements that aren’t mentioned in the form, please include as much information in the bottom fied. Our talented team of experts can help with almost any magnet requirements.

Can I choose the magnetisation direction?

Yes, you can choose the direction of magnetisation when ordering custom magnets.

The most common direction to magnetise magnets is axially. Axially magnetised magnets are magnetised through the length of the magnet, whereas diametrically magnetised magnets are magnetised through the width.

If you are unsure, please contact us and a member of our team will be happy to help.

What is the minimum order quantity?

We don’t have a minimum order quantity. However, our minimum spend for custom manufacturing is £100 due to design, moulding and manufacturing fees.

How are costs calculated?

The price of Neodymium goes up and down throughout the year and quotes are reflective of those changes. This means like-for-like quotes may differ throughout the year.

What are the size tolerance levels?

Tolerence levels determine slight differences in the size of your magnet. Our tolerance levels are 0.1mm+/-.

Can I choose heat tolerances?

Yes, we can produce magnets to most heat tolerences.

A magnet’s coercivity, or “Hci” refers to the magnets ability to withstand demagnetisation through high temperatures. When manufacturing magnets, a magnet’s coercivity is defined by the letters after the grade, for example, the “M” in N52M. Any magnets without a letter after the grade (i.e N35, N45, N52) have a heat tolerence of up to 80°C.

Available Heat Tolerences

No letter – 80°C
M – 100°C
H – 120°C
SH – 150°C
UH – 180°C
EH – 200°C
TH – 220°C

What is the returns policy?

If you have a change of heart and would like to cancel your order our team will do everything in their power to help. If manufacturing has started we cannot refund your purchase because the custom order has no resale value.
