Hey there! As a supplier of cutter blades 18mm, I often get asked about the materials used to make these blades. It's a super important topic because the material directly affects the blade's performance, durability, and cost. So, let's dive right in and explore the different materials commonly used for 18mm cutter blades.
High - Carbon Steel
One of the most popular materials for making 18mm cutter blades is high - carbon steel. High - carbon steel contains a relatively high percentage of carbon, usually between 0.6% and 1.5%. This extra carbon gives the steel several great properties.
First of all, high - carbon steel can be heat - treated to achieve a high level of hardness. A hard blade can hold its edge for a long time, which means it can make clean and precise cuts over an extended period. For example, when you're using an 18mm cutter blade to cut through cardboard, a high - carbon steel blade will stay sharp and cut smoothly without getting dull quickly.
However, high - carbon steel also has its drawbacks. It is more prone to rust compared to some other materials. That's why many high - carbon steel blades are coated with a protective layer to prevent corrosion. Despite this, if you're in a humid environment and don't take proper care of the blade, it can still start to rust.
Our 18mm SK2 Steel Snap - Off Blade is made of high - carbon SK2 steel. SK2 steel is a well - known high - carbon steel grade in the blade - making industry. It offers excellent edge retention and is suitable for a wide range of cutting tasks, from light - duty paper cutting to medium - duty plastic cutting.
Stainless Steel
Stainless steel is another common material for 18mm cutter blades. Stainless steel contains chromium, which forms a thin, invisible layer of chromium oxide on the surface of the blade. This layer protects the steel from rust and corrosion, making stainless steel blades ideal for use in wet or humid conditions.
Stainless steel blades are also relatively tough and resistant to chipping. They can withstand a certain amount of abuse without breaking or losing their shape. For instance, if you accidentally drop an 18mm stainless steel cutter blade on a hard surface, it's less likely to get damaged compared to a high - carbon steel blade.
But stainless steel has a trade - off. It is generally not as hard as high - carbon steel, which means the edge may not hold as well over time. So, for applications that require extremely sharp and long - lasting edges, high - carbon steel might be a better choice.
We have a variety of Cutter Blade 18mm made of stainless steel. These blades are great for general - purpose cutting, especially in environments where rust is a concern, like in a kitchen or a marine setting.
Carbide - Tipped
Carbide - tipped blades are a bit of a step up in terms of performance. These blades have a carbide tip brazed onto a steel body. Carbide is an extremely hard material, much harder than high - carbon steel or stainless steel.
The carbide tip provides an incredibly sharp and long - lasting edge. It can cut through very tough materials, such as ceramics, glass, and some metals. For example, if you're working on a construction site and need to cut through ceramic tiles, a carbide - tipped 18mm cutter blade will make the job much easier and more efficient.
The downside of carbide - tipped blades is the cost. Carbide is an expensive material, and the manufacturing process of carbide - tipped blades is more complex. So, these blades are usually pricier than high - carbon steel or stainless steel blades.
Ceramic
Ceramic blades are becoming more popular in certain applications. Ceramic is extremely hard and can hold an edge for a very long time. It is also chemically inert, which means it won't react with most substances, making it suitable for cutting food or other sensitive materials.
An 18mm ceramic cutter blade can make very precise cuts, especially when cutting thin materials like paper or film. However, ceramic is brittle. It can break easily if dropped or subjected to too much force. So, it's not suitable for heavy - duty cutting tasks.
Factors Affecting Material Choice
When choosing the material for an 18mm cutter blade, several factors come into play. The type of material you'll be cutting is crucial. If you're cutting soft materials like paper or fabric, a high - carbon steel or stainless steel blade might be sufficient. But if you're dealing with hard materials like metals or ceramics, a carbide - tipped blade would be a better option.
The environment in which the blade will be used also matters. If it's a wet or humid environment, stainless steel or a coated high - carbon steel blade is a good choice to prevent rust. And if you need to make a large number of cuts, a blade with good edge retention, like a high - carbon steel or carbide - tipped blade, will save you time and money in the long run.
