Rare Earth Metals Forecast
This last year has seen large fluctuations in rare earth metals pricing and some like PrNd and DyFe have more than doubled since October of last year. PrNd and DyFe are two metal components used in the manufacture of the very popular NdFeB (Neo) magnets.
In the month of October, PrNd rose by 16% and DyFe by 5% – with many factors driving the prices up including supply shortages, increased production costs and the continued growing demand.

Halbach Array Permanent Magnet Assemblies
Allstar Magnetics can work with your team to design and manufacture Halbach arrays for your permanent magnet assembly needs. Halbach arrays are an arrangement of permanent magnets that concentrates the field on one side of array and has a near zero field on the opposite side. This is achieved by alternating the polarity of the magnets and forcing the path of the flux lines on one side to combine and the opposite side to cancel each other out. These assemblies can be constructed in variety of different configurations such as linear, cylindrical, or circular.
Industry Applications
Linear applications include particle accelerators, free-electron lasers, linear motors, and any movement that requires planar motion. There are a variety of design that use cylindrical arrangements for higher power density and efficiency such as NMR, high torque motors and beam focusing applications. Halbach arrays can also be used to create gradient fields to channel electrons in medical and science applications.
Manufacturing Considerations
It is important to understand the required field, air gap, temperature at operation, life of the product, adhesive outgassing, magnet performance at both temperature, magnet performance in a magnetic field, mechanical constraints, tooling, allowable fringing, weight, size and budget.
Let us know how we can help with your custom magnetic needs.

Rapid Prototyping
Allstar offers rapid prototyping of custom machined permanent magnets and magnet assemblies. Companies often advertise rapid prototypes and then miss promised delivery dates. At Allstar we specialize in on-time-delivery and will meet your deadline requirements. Typical lead time is 4-5 weeks for magnets and 2-3 weeks for ferrites.

Featured Case Studies:
At Allstar it is not just parts, it is about achieving customer satisfaction. We specialize in solving problems.
Here are a few of the more unusual solutions:
A magnetic material was obsoleted over 60 years ago and Allstar was able to provide prototypes to create the exact custom blend.
View Research & Development Case Study
Custom designed magnetic assembly was a cost prohibitive and manufacturing nightmare until the customer brought the design to Allstar – see how they solved the issues.
View Assembly Case Study
An R&D wire wound prototype was built in the lab and company struggled to find suppliers that could meet the production scale volumes – see how Allstar quickly ramped to meet the demand.
