I. Core Material Comparison Table Material Weight Hardness/Toughness Hypoallergenic Price Features & Disadvantages Pure Titanium Extremely light Medium, slightly soft Excellent (medical grade) High Lightest, does not rust, does not cause allergies; general strength, prone to slight deformation Beta Titanium Very light High, excellent elasticity Excellent Medium-high elasticity Super strong, not easy to break, can be fine-tuned; slightly heavier than pure titanium Stainless Steel Medium hard, strong General

1、Comparison of core materials

table

material	weight	hardness	anti-allergy	price	Features & Disadvantages
pure titanium	extremely light	Medium, slightly soft	Excellent (Medical Grade)	Tall	Lightest, rust-free, and hypoallergenic; moderate strength, prone to minor deformation
β titanium	very light	High, extremely elastic	Excellent	Medium-high	It is highly elastic, durable, and can be finely adjusted; it is slightly heavier than pure titanium
Stainless steel	moderate	Hard, solid	general	Low	Cheap, durable, and available in various styles; slightly heavy, may cause allergy to sensitive skin
Monel alloy	moderate	韧性好	Poor	Medium-Low	Easy to process and weld; prone to allergies and rusting if the plating falls off
Nickel silver / copper alloy	biased toward	Soft, easy to process	poor	Low	Good texture, easy to polish; heavy, prone to oxidation, and allergenic

2、Distinguish in a simple sentence

Pure titanium: the lightest, the most expensive, and the most suitable for sensitive skin
Beta Titanium: elastic, durable, suitable for people who frequently bend and fold their glasses
Stainless steel: the king of cost-effectiveness, sturdy and durable
Monel: commonly used in old-fashioned metal frames, a mainstay in the mid-to-low end market
Copper alloy: commonly used for vintage, carved, and gold-plated styles

3、Purchase Recommendations

For those who are prone to allergies and wear dentures for a long time, pure titanium / β titanium is the preferred choice
For students who are prone to breaking glasses, β titanium (durable) is recommended
Pursuing cost-effectiveness and business simplicity → stainless steel
Vintage carved and gold-plated models → mostly made of copper alloy
