What is H in Tempered Glass?
H-rated tempered glass is the latest innovation in smartphone screens. It's highly resistant to scratches, cracks, and impact damage. The addition of H strengthens the glass, making it more durable and long-lasting. With H-rated tempered glass, you can now enjoy a smartphone that can withstand the tests of time and daily use.
The "H" in tempered glass represents the hardness level, specifically 9H hardness. The "H" here does not refer to the Moh’s hardness unit, but to the hardness unit of the pencil lead. The hardness of tempered glass film is usually between 6 and 7, and the hardness of qualified tempered glass film should be above 9H.

Tempered glass,also known as toughened glass, strengthened glass, reinforced glass, is a kind of strengthened glass that is rapidly cooled after being heated at high temperature. The tempered glass product has the characteristics of high strength, high stability, heat resistance, cold resistance and good safety. Its physical properties and chemical properties have been significantly improved, and it is widely used in construction, household appliances, furniture, electronics, automobiles and other fields.
Hardness test method for tempered glass
The hardness testing methods of tempered glass mainly include Vickers hardness and Moh’s hardness testing methods.
1. Vickers hardness test method
The Vickers hardness test uses an indenter of a specific shape and material to create indentations on the glass surface with a certain loading force, and then evaluates the hardness of the glass based on the size and shape of the indentations. This method is simple to operate and has accurate results, and is widely used in glass hardness testing
2. Moh’s hardness test method
The Moh’s hardness test determines the hardness of a material by comparing scratches between the material and minerals of known hardness. The hardness of tempered glass is usually between 5 and 6 on the Moh’s scale. This method is simple and easy to implement, but the results are greatly affected by human operating factors, so it is suitable for preliminary evaluation.
The hardness test of tempered glass usually uses Mohs hardness scale. The hardness of glass is around 6, while the hardness of qualified tempered glass film should be above 9H. In the Mohs hardness scale, 9H does not refer to the hardness of diamonds, but to the hardness unit of pencil lead.
In conclusion, the market for H-rated tempered glass is rapidly gaining momentum, driven by consumer demand for high-performing and long-lasting smartphone screens. As the technology behind this innovation continues to evolve and improve, it is expected to become a standard feature in all premium mobile devices. The market hotspots for H-rated tempered glass are Asia-Pacific and Europe, where smartphone sales are high and consumers are more tech-savvy. The future looks bright for this innovative technology, spearheading the growth of the mobile device market for years to come.
