Yo, what's up everyone! I'm a supplier of zinc alloy lever handles, and I often get asked about the chemical composition of the zinc alloy we use. So, I thought I'd write this blog to break it down for y'all.

First off, let's talk about why zinc alloy is such a great choice for lever handles. Zinc alloy has a bunch of awesome properties. It's strong, which means our lever handles can withstand a lot of wear and tear. It's also easy to mold, so we can create all sorts of cool designs for our handles. And it has a nice finish that looks good and can be coated or plated to match different interior styles.

Now, onto the chemical composition. The main element in the zinc alloy we use is, of course, zinc. Zinc usually makes up the majority of the alloy, typically around 85 - 95%. Zinc is a great base because it's relatively inexpensive, which helps keep the cost of our handles down without sacrificing quality. It also provides good corrosion resistance, so our lever handles won't rust easily, even in areas with high humidity.

But zinc alone wouldn't be enough to give the alloy all the properties we need. That's where the other elements come in. One of the most common additives is aluminum. Aluminum is usually present in the range of 3 - 6%. Adding aluminum to the zinc alloy makes it stronger and more ductile. Ductility is important because it allows the alloy to be shaped without breaking during the manufacturing process. It also helps improve the alloy's fluidity when it's melted, which makes it easier to cast into the complex shapes of our lever handles.

Another important element is magnesium, which is typically added in small amounts, around 0.02 - 0.05%. Magnesium plays a crucial role in controlling the grain structure of the zinc alloy. A fine - grained structure makes the alloy harder and more resistant to cracking. It also helps with the alloy's workability and can improve the overall surface finish of the handles.

Copper is another element that's sometimes added. Copper content can range from 1 - 3%. Copper increases the strength and hardness of the zinc alloy. It also gives the alloy a bit of color variation and can improve its wear resistance. So, when you're using our lever handles day in and day out, they'll stay looking good and functioning well.

Now, let me show you some of the great products we have. Check out our Modern Passage Rosette Zinc Alloy Door Handle. It's a sleek and modern design made with the high - quality zinc alloy we've been talking about. The chemical composition ensures that it's durable and looks great for years to come.

We also have Black Interior Door Handles. These handles are not only stylish but also made with the same carefully crafted zinc alloy. The unique black finish adds a touch of elegance to any interior.
