1. Product Overview
White Fused Alumina (WFA), also known as White Aluminum Oxide or White Corundum, is a high-purity synthetic abrasive widely used in industrial sandblasting and surface preparation.
For smartphone accessory manufacturing, White Fused Alumina can be used for sandblasting aluminum alloy frames, metal housings, camera rings, buttons, and other precision metal components.
Its sharp, angular particles provide effective cutting action, helping achieve a clean, uniform matte finish and consistent surface texture when properly matched with the blasting process.
2. Applications in Smartphone Accessories Manufacturing
A. Smartphone Aluminum Alloy Frames
- Creates a uniform matte surface.
- Improves surface appearance and texture.
- Removes minor surface contaminants.
- Prepares metal surfaces for subsequent finishing processes.
B. Mobile Phone Metal Housings
- Provides consistent surface roughness.
- Helps remove minor burrs and surface imperfections.
- Supports surface preparation before coating or other treatments.
C. Smartphone Camera Rings
- Suitable for controlled abrasive blasting of metal camera rings.
- Helps create a fine, uniform surface texture.
- Supports decorative matte finishing.
D. Metal Buttons and Small Accessories
- Suitable for surface finishing of small precision metal parts.
- Helps achieve a consistent appearance across batches.
- Can be evaluated for controlled deburring applications.
Application Note: The final surface finish depends on abrasive grit size, blasting pressure, nozzle distance, blasting angle, exposure time, and workpiece material. Sample testing is recommended before mass production.
