Borosilicate gauge glass and aluminosilicate glass differ in their manufacturing processes, pricing, and specifications

Borosilicate Gauge Glass and Aluminosilicate (Aluminium Silicon) Glass are both types of gauge glass used in various applications. Both types offer unique advantages, with borosilicate glass offering superior thermal resistance, and aluminosilicate glass offering superior hardness and scratch resistance.

Here’s different in terms of manufacturing process, applications, price, and specifications:

Manufacturing Process:

Borosilicate Glass: This type of glass is made by adding boron to the traditional glassmaking mix of silicate sand, soda, and ground limestone. During the manufacturing process, the ingredients are heated until they melt into a uniform mixture. Once the mixture cools, it forms a glass that is much more resistant to heat and chemical corrosion than regular glass.

Aluminosilicate Glass: The production process of aluminosilicate glass is similar to that of borosilicate, but aluminum oxide is used instead of boron. The aluminum oxide increases the chemical durability and hardness of the glass, making it more resistant to scratches and breakage.

Applications:

Borosilicate Glass: Given its superior resistance to heat and chemicals, borosilicate glass is often used in environments that demand durability and thermal resistance. This includes use in laboratory equipment, cooking and baking ware, high-intensity lighting, and in gauge glasses for steam boilers and tanks.

Aluminosilicate Glass: Due to its increased hardness and scratch resistance, aluminosilicate glass is commonly used in areas that require a strong, durable glass. It’s commonly used for smartphone screens, watch faces, and other consumer electronics. It also sees use in high-pressure gauge glasses.

Price:

In general, both borosilicate and aluminosilicate glasses are more expensive than ordinary glass due to the additional processing required and the superior properties they offer. The prices can vary widely based on the specific application, size, and volume of the order. Generally, aluminosilicate glass tends to be more expensive due to its increased durability and resistance to breakage.

Specifications:

Borosilicate Glass: This glass typically has excellent thermal resistance, allowing it to withstand temperatures up to 500 degrees Celsius. It also has low thermal expansion, meaning it doesn’t expand or contract much with temperature changes, preventing it from cracking under rapid temperature shifts.

Aluminosilicate Glass: This glass is highly durable, resistant to scratching, and can withstand high pressures. While it also has good thermal resistance, it doesn’t quite match borosilicate glass in this regard. However, its superior hardness and scratch resistance often make it the preferred choice for heavy-duty applications.
