Hey there! As a supplier of Liquid Level Floating Ball, I often get asked about the materials commonly used to make these nifty little devices. So, I thought I'd take a moment to share some insights on this topic.
1. Plastic
Plastic is hands - down one of the most popular materials for making liquid level floating balls. There are several types of plastics that are commonly used, each with its own set of advantages.
Polypropylene (PP)
Polypropylene is a lightweight and durable plastic. It's resistant to a wide range of chemicals, which makes it suitable for use in various industrial and domestic applications. For instance, in water treatment plants, polypropylene floating balls can be used to monitor the water level in tanks without getting corroded by the chemicals present in the water. It's also relatively inexpensive, which is a big plus for cost - conscious customers.
Polyethylene (PE)
Similar to polypropylene, polyethylene is another widely used plastic. High - density polyethylene (HDPE) is especially popular for liquid level floating balls. It has excellent impact resistance, so it can withstand rough handling and the occasional bump in the tank. HDPE floating balls are often used in agricultural applications, like in water storage tanks for irrigation systems. They can handle the constant exposure to water and are not easily damaged by the elements.
PVC (Polyvinyl Chloride)
PVC is a rigid plastic that offers good chemical resistance. It's often used in situations where the liquid being monitored is not too aggressive. For example, in some small - scale residential plumbing systems, PVC floating balls can be used to control the water level in a sump pump. However, it's important to note that PVC may not be suitable for extremely high - temperature applications.
2. Stainless Steel
Stainless steel is a go - to material when you need a high - strength and corrosion - resistant floating ball.
304 Stainless Steel
304 stainless steel is a common choice. It contains chromium and nickel, which give it good resistance to rust and oxidation. This type of floating ball is often used in industrial settings where the liquid is corrosive, such as in chemical processing plants. The high strength of 304 stainless steel also means that it can be used in large - scale tanks without deforming under the pressure of the liquid.
316 Stainless Steel
316 stainless steel is even more corrosion - resistant than 304. It has a higher molybdenum content, which makes it suitable for use in more aggressive environments, like in marine applications. If you're monitoring the level of seawater in a storage tank on a ship, a 316 stainless steel floating ball would be a great option as it can withstand the saltwater corrosion.
3. Brass
Brass is an alloy of copper and zinc, and it's known for its good machinability and corrosion resistance.
Brass floating balls are often used in applications where a certain level of conductivity is required. For example, in some electrical systems that use liquid level sensors, brass floating balls can help in completing an electrical circuit when the liquid level reaches a certain point. They are also aesthetically pleasing, so they can be used in applications where appearance matters, like in some decorative water features.
4. Ceramic
Ceramic floating balls are less common but have their own unique advantages.


Ceramics are extremely resistant to wear and corrosion. They can withstand high temperatures and are chemically inert. In some high - temperature industrial processes, like in foundries or glass manufacturing plants, ceramic floating balls can be used to monitor the level of molten materials. However, they are relatively brittle compared to other materials, so they need to be handled with care.
5. Composite Materials
Composite materials are becoming more popular in the manufacturing of liquid level floating balls.
These materials are made by combining two or more different materials to get the best properties of each. For example, a composite floating ball might have a plastic core for light weight and a stainless - steel outer layer for corrosion resistance. This way, you can get a floating ball that is both durable and cost - effective.
