Sintered neodymium magnets are the main line of Huatai Xinding (Beijing) Metal Materials Co., Ltd., a Beijing company trading under the brand Atech (HTXD). The company's product pages present sintered neodymium magnets as the strongest magnetic material commercially available today, built from the alloy neodymium, iron and boron, Nd2Fe14B. This site organises that published range by shape, by grade temperature series, by magnetization direction and by field of use, so that a buyer can check a specification against the published range before writing an inquiry.

Shapes by geometry, each with its own published range
The range is published in six shape families: disc and cylinder, block and plate, ring and tube, arc and segment, sphere, and countersunk. A seventh route, custom shapes, is handled as a made-to-order inquiry rather than as a stocked shape with a published size table. The distinction matters, because a dimension that belongs to one shape family cannot be carried over to another. A disc diameter range, for example, says nothing about a ring inner diameter, and a block thickness range says nothing about a sphere diameter. Every detail page on this site therefore repeats only the range that belongs to its own shape, with its own tolerances and its own magnetization directions.
Buyers who are still choosing a shape should start with the shape comparison guide, which places the six published ranges side by side without merging them. Buyers who already know their shape can go straight to the detail page for that shape and check the published minimum and maximum dimensions, the standard and minimum tolerances, and the magnetization directions listed for that shape. Where a shape has no published size table, this site says so plainly instead of filling the gap with a figure from another shape.
Disc / Cylinder Magnets
Diameter 1.2–220 mm; height 0.5–50 mm. Axial, diametrical and axial in segments.
Block / Plate Magnets
Length 2.0–250 mm; width 1.5–150 mm; thickness 0.5–50 mm.
Ring / Tube Magnets
Outer diameter 3.0–200 mm; inner diameter 1.5–150 mm; height 0.5–50 mm.
Arc / Segment Magnets
Outer diameter, inner diameter and angle are customized. No product photograph is published for this shape on this site.
Sphere Magnets
Diameter 1–60 mm. Axial and diametrical magnetization.
Countersunk Magnets
Round and rectangular forms customized; countersunk hole M1–M10.
Custom-Shaped Magnets
Made to order. No size table is published for custom shapes — please confirm dimensions before ordering.
Magnetic Assemblies
Eight category names listed from the company navigation: mounting, hook, threaded, countersunk/counterbore pot, channel, rubber coated, adhesive and PVC waterproof. Category names only — no per-category parameters are published here.
Grades and working temperature, stated as a shared table
The company's shape pages carry the same grade maximum working temperature table, and this site reproduces it as a shared table wherever grades are discussed. The N35–N52 series is listed at 80°C, the M series at 100°C, the H series at 120°C, the SH series at 150°C, the UH series at 180°C and the EH series at 200°C. Because the table is shared across the shape pages, it must not be read as a measurement taken on one single shape, and it must not be extended into a performance claim for a particular grade beyond the temperature figure itself. The company's sintered page also carries demagnetization curve charts; curve values were not transcribed page by page, so no curve numbers appear in this site's text.
Coating is treated the same way. A coating illustration appears on the company's sintered page, but coating type names were not transcribed item by item, so this site names no coating type. If coating matters to your application, please confirm coating requirements before ordering, and include the operating environment in the same inquiry so the answer can be specific.
Fields of use, stated as categories only
The company's site lists six fields of use: automotive and transportation, clean energy, consumer products, electronics and electrical appliances, industrial fields, and medical devices. This site uses those six headings only as application categories. They are not export results, not customer lists and not case studies, and no page on this site presents them as such. Each field has its own guide page that explains what to check before ordering for that kind of use, without naming vehicle models, device models or performance figures that the published pages do not support.
How to use this site
First, confirm the shape and read only that shape's detail page. Second, check the shared grade temperature table and choose a temperature series to ask about, rather than assuming a grade from its name. Third, state the magnetization direction exactly as listed for that shape, because the same direction word can belong to different shapes with different geometry. Fourth, send the full specification for review, including dimensions, grade series, magnetization direction, quantity for discussion, and any coating or operating-environment requirement. Please confirm minimum order quantity and lead time before ordering.
