目前，眼鏡架材料主要分為鈦材、高級合金、記憶、板材、其它材料五類。

1、鈦是一種純性金屬，比重4.5，韌度高，無磁性反應(yīng)，對皮膚不過敏，廣泛使用于太空技術(shù)、珠寶飾品、手術(shù)用具等領(lǐng)域，是眼鏡行業(yè)最高端的材料；

2、重量較一般金屬輕48%，解除鼻梁負(fù)擔(dān)，高強度，不易刮傷磨損，有良好的耐腐蝕性和可塑性；

3、相對于其它金屬材料不易變形與褪色，穩(wěn)定性強，突出尊貴品味與高雅氣質(zhì)。

4、鈦材鏡架主要有純鈦、鈦合金和β鈦鏡架三種。純鈦鏡架全部采用99％高純度的鈦材制成；鈦合金鏡架的鏡圈或是主體部分為鈦合金，牢固性能好；β鈦鏡架的鏡圈或是主體部分為β鈦，具有較高的彈性和強度。

擴展閱讀：純鈦眼鏡架和鈦合金的優(yōu)缺點

答：合金好。

合金輕巧，耐腐蝕。對皮膚無害，而且不易變形。

純鈦比重一般是4.5，而合金是8.9，材料相當(dāng)于鈦合金的一半。所以做出來的眼鏡架用手掂起來比較輕，這是區(qū)分這兩種眼鏡架最簡單的方法。鈦合金眼鏡架會相對于純鈦眼鏡架要稍微重一些，但是這兩都是優(yōu)質(zhì)的材料，所以從外觀上來看給人的感覺比較舒服。

【英文介紹/For English】：

At present, glasses frame materials are mainly divided into five categories: titanium material, advanced alloy, memory, sheet metal, and other materials.

1. Titanium is a pure metal with a specific gravity of 4.5, high toughness, no magnetic reaction, and no skin allergies. It is widely used in space technology, jewelry, surgical appliances and other fields, and is the most high-end material in the eyewear industry;

2. The weight is 48% lighter than that of ordinary metals, which relieves the burden on the bridge of the nose, high strength, not easy to scratch and wear, and has good corrosion resistance and plasticity;

3. Compared with other metal materials, it is not easy to deform and fade, and has strong stability, highlighting the noble taste and elegant temperament.

4. Titanium frames mainly include pure titanium, titanium alloy and beta titanium frames. The pure titanium frames are all made of 99% high-purity titanium; the mirror ring or main part of the titanium alloy frame is titanium alloy, which has good firm performance; the mirror ring or main part of the beta titanium frame is beta titanium, Has high elasticity and strength.
