The Truth About Titanium, Part 2: \u201cTitanium is light, but actually\u2026 aluminum is even lighter.\u201d<\/h1>\n\n\n\n

Have you ever held a titanium bolt?
The first time I touched one, I honestly thought, \u201cWait\u2026 is this plastic?\u201d<\/p>\n\n\n\n

It has a lightness and texture that hardly feels like metal.
You should definitely try holding titanium in your hand at least once.<\/p>\n\n\n\n

Titanium is light! But aluminum is even lighter.<\/h3>\n\n\n\n

Titanium feels surprisingly light for how it looks, but\u2026<\/p>\n\n\n\n

actually, aluminum is even lighter than titanium!<\/p>\n\n\n\n

The specific gravity of aluminum, titanium, and steel is:
2.7\uff1a4.5\uff1a7.9<\/p>\n\n\n\n

To put it simply\u2014
if you had the same volume of steel, titanium, and aluminum:<\/p>\n\n\n\n

    \n
  • If steel weighs 100 g:<\/li>\n\n\n\n
  • Titanium would weigh 57 g<\/li>\n\n\n\n
  • Aluminum would weigh 34 g
    <\/li>\n<\/ul>\n\n\n\n

    In other words,
    titanium weighs 57% as much as steel, while aluminum weighs 34% as much as steel.<\/p>\n\n\n\n

    Strength difference between aluminum and titanium<\/h3>\n\n\n\n

    If aluminum is lighter, then it might seem better to use aluminum for bolts and nuts as well.
    However, it\u2019s not that simple because of strength requirements.<\/p>\n\n\n\n

    The titanium alloy commonly used for bolts, Ti-6Al-4V, has a strength of about 900\u2013950 MPa.
    In comparison, high-strength 7075 aluminum is around 570 MPa.
    That means titanium is roughly 1.6 times stronger.<\/p>\n\n\n\n

    As for 6061 aluminum, which is the most common material used for aluminum bolts, its strength is about 310 MPa.
    That is only about one-third the strength of titanium.<\/p>\n\n\n\n

    So, when designing for the same required strength, titanium can use a smaller cross-sectional area, reducing overall mass.
    As a result, it can sometimes end up lighter than aluminum.<\/p>\n\n\n\n

    That said, manufacturing is never that simple.
    The balance between strength and weight is important for each individual part.

    Diet Methods vs. Titanium Bolts<\/h3>\n\n\n\n

    You sometimes hear people say,
    \u201cInstead of buying expensive titanium bolts, it\u2019s more effective for the rider to lose weight.\u201d<\/p>\n\n\n\n

    But is that really true?
    Let\u2019s take a closer look.<\/p>\n\n\n\n

    \u201cA famous diet program that was once popular in Japan\u201d
    \u201cOur (Moto Rockman) titanium bolts\u201d<\/p>\n\n\n\n

    Let\u2019s compare the cost performance of these two.<\/p>\n\n\n\n

    \n
    \n

    \u3010Diet program\u3011
    According to blogs written by people who joined that program,
    the target weight loss for the 2-month course was \u221213 kg.<\/p>\n\n\n\n


    The total cost was reportedly \u00a5445,000.
    That means losing 1 kg cost approximately \u00a534,230.<\/p>\n\n\n\n

    \u3000\u3000<\/p>\n<\/div>\n\n\n\n

    \n

    \u3010moto rockman tianiumbolt\u3011
    OEM bolt M10\u00d760 \u2192 42 g
    Moto Rockman M10\u00d760 \u2192 23 g
    That\u2019s a weight reduction of 19 g.

    Since this titanium bolt costs \u00a52,050,
    the cost comes to \u00a5107.8 per gram.
    That means reducing 1 kg would cost \u00a5107,800<\/p>\n<\/div>\n<\/div><\/div>\n\n\n\n

    So, in terms of cost performance, the diet method wins by a huge margin.
    Unfortunately, this turned out to be a disappointing result for us as a company that specializes in titanium products.<\/p>\n","protected":false},"author":1,"featured_media":15385,"template":"","class_list":["post-15251","tips","type-tips","status-publish","has-post-thumbnail","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/tsrjp.com\/en\/wp-json\/wp\/v2\/tips\/15251","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tsrjp.com\/en\/wp-json\/wp\/v2\/tips"}],"about":[{"href":"https:\/\/tsrjp.com\/en\/wp-json\/wp\/v2\/types\/tips"}],"author":[{"embeddable":true,"href":"https:\/\/tsrjp.com\/en\/wp-json\/wp\/v2\/users\/1"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/tsrjp.com\/en\/wp-json\/wp\/v2\/media\/15385"}],"wp:attachment":[{"href":"https:\/\/tsrjp.com\/en\/wp-json\/wp\/v2\/media?parent=15251"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
