China-Made Alternative Products

China-made alternatives are compared by deep ion-exchange capability, post-strengthening surface compression profile, hardness, edge strength, thickness and the customer’s rough-surface drop test.

Recommended matching criteria:

Chinese high-strength aluminosilicate cover glass
Deep chemical strengthening
2D/2.5D shaping and reliability tests

Customization and Processing

Round wafers, square panels, windows and custom outlines
Precision cutting, edge grinding, chamfering and laser processing
Single- or double-side polishing, thinning, cleaning and marking
TTV, warp, roughness, dimensional and optical inspection to agreed criteria

Qualification Note

Important: “Alternative” means a candidate selected for the same application target. It does not mean an automatic drop-in replacement or identical composition. Final acceptance is based on agreed specifications, samples, test reports and process verification.

Request Material Matching

Manufacturer and product names are used only to identify reference materials and technical targets. Semicon Global Tech is an independent supplier and does not claim manufacturer authorization unless explicitly stated. Original-grade data and China-made alternative specifications are presented separately; supply specifications are confirmed by quotation, COA and approved samples.
