As a dedicated supplier of eccentric latches, I've witnessed firsthand the diverse needs and preferences of our customers. Eccentric latches are a crucial component in various industries, from marine applications to industrial machinery. They offer a reliable and efficient way to secure doors, hatches, and panels, ensuring safety and functionality. In this blog, I'll delve into the materials commonly used to make eccentric latches, exploring their properties, advantages, and ideal applications.
Stainless Steel
Stainless steel is one of the most popular materials for eccentric latches, and for good reason. It is highly resistant to corrosion, making it ideal for use in harsh environments, such as marine and outdoor applications. Stainless steel is also strong and durable, capable of withstanding heavy use and abuse.
There are several grades of stainless steel, each with its own unique properties. The most common grades used for eccentric latches are 304 and 316. Grade 304 stainless steel is a general-purpose alloy that offers good corrosion resistance and strength. It is suitable for most applications, including indoor and outdoor use. Grade 316 stainless steel, on the other hand, contains molybdenum, which enhances its corrosion resistance, especially in saltwater environments. It is commonly used in marine applications, such as boats and yachts.
One of the key advantages of stainless steel eccentric latches is their aesthetic appeal. They have a sleek and modern look that can enhance the appearance of any application. Stainless steel is also easy to clean and maintain, making it a practical choice for busy environments.
If you're looking for a high-quality eccentric latch for a marine application, I recommend considering a Stainless Steel Vent. These vents are made from high-grade stainless steel and are designed to provide reliable ventilation while also securing the hatch or door.

Aluminum
Aluminum is another popular material for eccentric latches, especially in applications where weight is a concern. Aluminum is lightweight, yet strong and durable, making it an ideal choice for aerospace, automotive, and marine applications.
One of the key advantages of aluminum eccentric latches is their corrosion resistance. Aluminum naturally forms a protective oxide layer on its surface, which helps to prevent rust and corrosion. This makes aluminum latches suitable for use in outdoor and marine environments.
Aluminum is also easy to machine and fabricate, allowing for complex designs and shapes. This makes it a popular choice for custom applications, where unique latch designs are required.
However, aluminum is not as strong as stainless steel, and it may not be suitable for applications that require high strength and durability. In addition, aluminum is more expensive than some other materials, such as steel, which may make it less cost-effective for some applications.
If you're looking for a lightweight and corrosion-resistant eccentric latch for a marine application, I recommend considering a Swivel Hasp. These hasps are made from high-quality aluminum and are designed to provide a secure and reliable locking solution for hatches and doors.
Brass
Brass is a popular material for eccentric latches, especially in applications where aesthetics are important. Brass has a warm, golden color that can add a touch of elegance to any application. It is also highly resistant to corrosion, making it suitable for use in outdoor and marine environments.
One of the key advantages of brass eccentric latches is their machinability. Brass is easy to machine and fabricate, allowing for complex designs and shapes. This makes it a popular choice for custom applications, where unique latch designs are required.
However, brass is not as strong as stainless steel or aluminum, and it may not be suitable for applications that require high strength and durability. In addition, brass is more expensive than some other materials, such as steel, which may make it less cost-effective for some applications.
If you're looking for a stylish and corrosion-resistant eccentric latch for a marine application, I recommend considering a Stainless Steel Rod Holder. These rod holders are made from high-quality brass and are designed to provide a secure and reliable way to hold fishing rods on boats and yachts.
Plastic
Plastic is a versatile material that is commonly used for eccentric latches, especially in applications where cost is a concern. Plastic latches are lightweight, inexpensive, and easy to manufacture, making them a popular choice for a wide range of applications.
There are several types of plastic that can be used for eccentric latches, including polycarbonate, nylon, and acetal. Each type of plastic has its own unique properties, such as strength, durability, and chemical resistance.
One of the key advantages of plastic eccentric latches is their resistance to corrosion. Plastic does not rust or corrode, making it suitable for use in outdoor and marine environments. Plastic is also easy to clean and maintain, making it a practical choice for busy environments.
However, plastic is not as strong as metal, and it may not be suitable for applications that require high strength and durability. In addition, plastic can be prone to cracking and breaking under heavy use or extreme temperatures.
Conclusion
In conclusion, there are several materials that can be used to make eccentric latches, each with its own unique properties, advantages, and ideal applications. Stainless steel is a popular choice for its corrosion resistance, strength, and durability, making it suitable for a wide range of applications, including marine and outdoor use. Aluminum is lightweight and corrosion-resistant, making it a popular choice for aerospace, automotive, and marine applications. Brass is a stylish and corrosion-resistant material that is commonly used in applications where aesthetics are important. Plastic is a versatile and inexpensive material that is commonly used in applications where cost is a concern.
