Recently, eyewear manufacturers around the world can take advantage of lots of materials to make eyeglass frames. Regular plastics and metals are most commonly and traditionally used, such as: cellulose acetate, propionate and nylon. And now there are also available new types of plastics and metals, like memory metal and memory plastic. There are still various unusual frame materials, including wood and even stone. Among all these materials possible to make eyeglass frames, stainless steel is a regular but special style.
This material has exclusive features or advantages. Stainless eyeglasses just refer to spectacles that have a stainless frame. Comparing with the other material frames, the superiority is rooted that sunglasses usually have large lenses which require a strong frame. Making a comparison between regular metals and plastics, eyeglasses designers and manufacturers may naturally find that the first group features better strength. This briefly explains that leading role gained by stainless sunglasses in the current market.
Widely used in the eyewear industry, stainless steel features lightness, low toxicity and strength. In addition, most of the stainless steel frames are nickel-free and thus hypoallergenic. Also as we know, stainless steel is exactly a steel alloy with a minimum of 10.5 or 11% chromium. In typical, the content of chromium ranges from 10 to 30 percent. Of course, the major ingredient is steel. And in some cases, other elements may be added. In addition to the above features, stainless eyeglasses have also excellent resistance to corrosion, abrasion and heat. Why is this material able to provide such valuable features or benefits? Well, it is the chromium that exactly matters. This ingredient added to regular steel makes this material stain-proof. To a high degree, this is considered as the most valuable advantage boasted by this alloy. Some people even call it corrosion-resistant steel, when the alloy type and grade are not stated.
Since the major element is regular steel, stainless steel has all of the properties of steel. Those extra benefits or attributes are contributed by the added ingredient. Stainless steel belongs to metal frames, which can benefit from several advanced materials which feature strength and other advantages. Stainless steel is an alloy that is hypoallergenic, lightweight and strong. In particular, this material used in sunglass frames can be corrosion-resistant. This attribute is unparalleled by other materials.
In addition, titanium is the better material than stainless steel. It has similar features and better more. Especially, the extreme flexibility and it offered by the popularity of memory titanium frames is incomparable by other metals. For example: NT2032 and LT1046 are pure titanium eyeglasses frames, RB1029 and NB2038 are bendable titanium frames. You can’t miss it and buy those from https://www.cheapglasses123.com. |
