Product Overview
Brass hemispheres carry a high reflective accent that suits brass door knockers, lampshades, jewellery, sculpture and church roof work.
Stamping press shapes the sheet in a die, then the stamped edge is trimmed to a precise hemispherical shape. Trimming leaves the edge smooth without burrs, and the half ball is then mirror polished or left raw. Water pressuring covers everything above ∅200mm at any size, with the seam ground and polished out.
Key Benefits
- Durable H62 brass alloy Stamping Press Made with mirror polished finished.
- Metric and Unified Thread are both available.
- MOQ:required-50PCS.
- Delivery Time:7days for Scheduled production.
Application Scenarios
- Door knockers and architectural hardware
- Lampshades
- Jewellery components
- Sculpture
- Church roof and spire elements
Who It Is For
- Architectural hardware makers
- Lighting manufacturers
- Jewellers
- Heritage and church restoration contractors
Problems It Solves
- A rough stamped edge will not sit flat against a fitting. The edge is trimmed precisely and left burr free.
- Brass tone varies between suppliers. We use H62 alloy consistently.
- Large brass domes need tooling. Water pressuring covers ∅200mm and up with no mould limit.

Materials
We form spheres and hemispheres in AISI 304, AISI 316 and AISI 316L stainless steel, Q235 carbon steel, H62 brass alloy and A6061 aluminium alloy. The alloy decides corrosion resistance, weight and how the surface takes a polish.
For this product the standard specification is H62 Brass Alloy. Tell us the site conditions and we will confirm whether a different grade is worth the cost.
Manufacturing Process
Forming happens by stamping press, water pressuring, spinning or hand assembling. Two halves are joined at the equator, the weld is ground, and the surface is finished last, after any cutting or drilling has been done.
Quality Control
Incoming material
Alloy and sheet thickness are checked against the order before any blank is cut.
Forming check
Diameter and wall are measured after pressing, spinning or water pressuring.
Weld and grind
The equator weld is inspected, then welds and burrs are ground off before finishing.
Surface inspection
Every piece is inspected for scratches, dents and polish consistency under light.
Packing
Protective packing is built around the diameter and weight, and photographs are sent before dispatch.
Customisation Options
- Diameter and wall thickness to your drawing, with no mould limit above ∅200mm
- Metric and unified threaded holes, drilled apertures and perforated patterns
- Welded base tubes, base plates, internal ribs and pedestals
- Mirror, brushed, sandblasted, etched, electroplated, PVD colour or spray painted finishes
- Logos, lettering and world maps by sandblasting, etching, laser cutting or plasma cutting
- LED kits fitted inside the sphere
- Segmentation into quarters or eighths for sizes above container limits

Comparing forming routes rather than products? The process guide sets out size, thickness, seam and mould limit for each.
Use Guide
Confirm the diameter first
Diameter drives the forming route, the wall thickness, the price and the freight mode. Settle it before anything else.
Match the alloy to the site
304 inland, 316 near salt water or pools, Q235 where a rust patina is wanted, brass or aluminium where weight or colour matters.
Choose the finish last
Finishing always happens after forming, welding, cutting and grinding, so pattern edges stay clean.
Plan the fixing
Tell us whether the piece is bolted, threaded, welded to a base tube or suspended, and we build the fitting into the part.
Check the shipping limit
∅2200mm fits a container, ∅3500mm fits a flat rack, and larger spheres are segmented with bolted ribs.
