Pure titanium is stronger and more rigid with a distinctive premium weight; beta-titanium is more flexible, lighter, and springs back to shape.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is no universal &#8220;better&#8221; \u2014 the right choice depends on your frame design, target customer, and price point.

Beta-titanium = flexible and springy.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Both are titanium alloys, but they are engineered for different personalities. Pure titanium frames feel substantial and hold their shape firmly; beta-titanium frames are feather-light and return to shape after bending.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Side-by-Side Comparison<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Property<\/th><th>Pure Titanium<\/th><th>Beta-Titanium<\/th><\/tr><\/thead><tbody><tr><td>Common designation<\/td><td>CP (commercially pure) titanium<\/td><td>Ti-13V-11Cr-3Al or similar beta alloys<\/td><\/tr><tr><td>Typical frame weight<\/td><td>10-14g<\/td><td>7-10g<\/td><\/tr><tr><td>Flexibility<\/td><td>Rigid, minimal flex<\/td><td>Highly flexible, returns to shape<\/td><\/tr><tr><td>Springback<\/td><td>Moderate<\/td><td>High<\/td><\/tr><tr><td>Strength<\/td><td>Higher tensile strength<\/td><td>Lower tensile strength, higher elongation<\/td><\/tr><tr><td>Fatigue resistance<\/td><td>Good<\/td><td>Excellent (bends without breaking)<\/td><\/tr><tr><td>Hypoallergenic<\/td><td>Yes<\/td><td>Yes<\/td><\/tr><tr><td>Corrosion resistance<\/td><td>Excellent<\/td><td>Excellent<\/td><\/tr><tr><td>Cost per kg<\/td><td>Lower (8-12x steel)<\/td><td>Higher (12-18x steel)<\/td><\/tr><tr><td>Machining difficulty<\/td><td>Difficult<\/td><td>More difficult (work-hardens faster)<\/td><\/tr><tr><td>Frame styles best suited<\/td><td>Classic, elegant, rimless, semi-rimless<\/td><td>Sport, flexible temple designs, active lifestyle<\/td><\/tr><tr><td>Typical retail positioning<\/td><td>Premium classic<\/td><td>Premium performance<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">What Each Material Feels Like in Practice<\/h3>\n\n\n\n<h4 class=\"wp-block-heading\">Pure Titanium Frames<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">When you pick up a pure titanium frame, you notice the weight first \u2014 not heavy, but substantial. The frame sits firmly on the face and holds its shape through daily wear.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Best uses:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Rimless and semi-rimless frames (titanium&#8217;s rigidity holds lenses securely)<\/li>\n\n\n\n<li>Classic rectangular and oval optical frames<\/li>\n\n\n\n<li>Premium collections where &#8220;solid craftsmanship&#8221; is the brand story<\/li>\n\n\n\n<li>Customers who prefer a frame that feels present, not invisible<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Watch out for:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Not suitable for highly flexible designs \u2014 the material resists bending<\/li>\n\n\n\n<li>Adjustments require more force (though still cold-adjustable)<\/li>\n\n\n\n<li>On very thin profiles, rigidity can feel stiff at the temple hinge<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Beta-Titanium Frames<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Pick up a beta-titanium frame and you might think it is broken \u2014 the temples bend almost effortlessly and spring back.

A temple designed to bend at 30 degrees may spring to 27 degrees after release. Factories must compensate for springback in the design phase \u2014 a capability not every factory has.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">Cost Impact<\/h4>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th><\/th><th>Pure Titanium<\/th><th>Beta-Titanium<\/th><\/tr><\/thead><tbody><tr><td>Raw material cost<\/td><td>8-12x steel<\/td><td>12-18x steel<\/td><\/tr><tr><td>Machining cost<\/td><td>2-3x steel<\/td><td>3-4x steel<\/td><\/tr><tr><td>Scrap rate<\/td><td>30-45%<\/td><td>35-50%<\/td><\/tr><tr><td>Typical per-frame premium over steel<\/td><td>+$6-12<\/td><td>+$10-18<\/td><\/tr><tr><td>Typical retail uplift over steel<\/td><td>+$30-60<\/td><td>+$50-90<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The per-frame cost difference between pure and beta titanium is roughly $4-6 at manufacturing \u2014 small per unit, but significant across a full collection order.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">How to Choose for Your Collection<\/h3>\n\n\n\n<h4 class=\"wp-block-heading\">Choose pure titanium if:<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Your brand positions as\u00a0<strong>classic premium<\/strong>\u00a0\u2014 craftsmanship, solidity, heritage<\/li>\n\n\n\n<li>You design\u00a0<strong>rimless or semi-rimless<\/strong>\u00a0frames<\/li>\n\n\n\n<li>Your target customer values a\u00a0<strong>substantial, quality feel<\/strong><\/li>\n\n\n\n<li>You are creating a\u00a0<strong>capsule collection<\/strong>\u00a0of timeless styles<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Choose beta-titanium if:<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Your brand positions as\u00a0<strong>performance or lifestyle<\/strong>\u00a0\u2014 sport, travel, daily active wear<\/li>\n\n\n\n<li>You design\u00a0<strong>flexible or sport-specific<\/strong>\u00a0frames<\/li>\n\n\n\n<li>Your customers have\u00a0<strong>broken rigid frames<\/strong>\u00a0or need durability<\/li>\n\n\n\n<li>You want the\u00a0<strong>lightest possible frame<\/strong>\u00a0on the market<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Consider mixing:<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Many premium brands offer both: pure titanium for the classic optical line, beta-titanium for the sport and flexible line. This covers both customer personalities under one brand roof.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Frequently Asked Questions<\/h3>\n\n\n\n<h4 class=\"wp-block-heading\">Can you tell the difference by weight alone?<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Usually yes. Pure titanium frames run 10-14g; beta-titanium runs 7-10g. The difference is noticeable when comparing side by side.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Is beta-titanium weaker because it&#8217;s more flexible?<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">No. Flexibility is not weakness. Beta-titanium&#8217;s high elongation means it bends further before breaking \u2014 which is why it survives impacts that crack rigid frames.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Are both hypoallergenic?<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. Both are biocompatible and do not contain nickel. Confirm the actual alloy composition with your supplier \u2014 some &#8220;titanium&#8221; frames are coated steel.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Which holds its adjustment better?<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Pure titanium. Its rigidity means adjustments stay put. Beta-titanium&#8217;s springback resists adjustment \u2014 it tends to return to its original shape.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Is beta-titanium always more expensive?<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, at both material and manufacturing levels. Expect roughly 30-50% higher frame cost than pure titanium.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\"><a
