It must also be said that none of these metals is as strong as diamond, but this carbon structure is not a metal.<\/p>\n\n\n\n<p>So, in this blog post we tell you about the four determinants of a metal&#8217;s strength and which are the hardest.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Determinants of metal strength<\/h2>\n\n\n\n<p>When talking about the strength or hardness of a metal, we could be talking about these four properties:<\/p>\n\n\n\n<ol class=\"wp-block-list\" start=\"1\">\n<li><strong>Tensile strength<\/strong>. This is the maximum tensile stress that a body can withstand before breaking.<\/li>\n\n\n\n<li><strong>Compressive strength<\/strong>. This is the ability of a material to withstand loads that tend to reduce its size, in other words, to compress. It is opposed to tensile strength, which is defined as the ability to withstand loads that tend to elongate, resisting tension.<\/li>\n\n\n\n<li><strong>Impact strength<\/strong>. The ability of a material to resist impact without breaking.<\/li>\n\n\n\n<li><strong>Brinell hardness<\/strong>. This is a scale for measuring the hardness of a material by means of the indentation method, i.e. it consists of applying a constant force for a given time (10-30 seconds) using a tungsten carbide ball of 2.5 to 10 mm in diameter, measuring the penetration of an object in the material to be studied.<\/li>\n<\/ol>\n\n\n\n<p>In this article we analyse <strong>which are the hardest according to<\/strong> the latter, <strong>the Brinell hardness<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What are the hardest metals<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Tungsten<\/h3>\n\n\n\n<p><a href=\"https:\/\/scrapad.com\/en\/materials\/tungsten\/\" target=\"_blank\" rel=\"noreferrer noopener\">Tungsten<\/a> is undoubtedly <strong>one of the hardest metals found in nature<\/strong>. It is known as a <strong>rare element<\/strong>, but once purified, it becomes more workable. It has a very high melting temperature of 3,422\u00b0C and an even higher boiling point of 5,930\u00b0C. It is often used to create alloys and alloy metals.<\/p>\n\n\n\n<p>It is often used <strong>to create high-speed or hard alloys<\/strong>, such as high-speed steel, increasing its protection against abrasion and improving electrical conductivity.<\/p>\n\n\n\n<p>Because it is the hardest metal, it is used to make the machining inserts with which all other metals, such as steel, bronze, etc., are processed and worked.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Iridium<\/h3>\n\n\n\n<p>Iridium is another <strong>metal<\/strong> with similar characteristics to tungsten, such as its <strong>resistance to melting and its high density<\/strong>. It belongs to the <strong>platinum group<\/strong>.<\/p>\n\n\n\n<p>Its melting temperature exceeds 2,000\u00b0C, which makes it quite brittle. It is also <strong>one of the rarest elements on earth<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Steel<\/h3>\n\n\n\n<p><a href=\"https:\/\/scrapad.com\/en\/materials\/iron-steel\/\" target=\"_blank\" rel=\"noreferrer noopener\">Steel<\/a> is the <strong>first, but not the purest, hardest and strongest metal alloy<\/strong>. Because of the many variations and levels of quality that steel can take, <strong>there is no uniform hardness value<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Osmium<\/h3>\n\n\n\n<p>Osmium also <strong>belongs to the platinum group of metals<\/strong>, and has a high density, being <strong>the densest naturally occurring metal on earth<\/strong>. Moreover, it does not melt until it reaches a very high temperature of 3,033\u00baC, which makes it difficult to work with this metal.<\/p>\n\n\n\n<p>When <strong>alloyed with other metals of the same group<\/strong> to which it belongs, it <strong>acquires great hardness and durability<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Chromium<\/h3>\n\n\n\n<p>Chromium is known for its <strong>scratch resistance<\/strong>. It is easier to handle compared to platinum group metals and is <strong>found in common alloys, such as steel<\/strong>. Chromium influences many properties of the final material and can be combined with other elements to modify them.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Titanium<\/h3>\n\n\n\n<p>Titanium is <strong>considered a very hard metal with an excellent strength-to-weight ratio<\/strong>. Even in its pure form, it is harder than some types of steel.<\/p>\n\n\n\n<p>It can also be alloyed with other elements such as <a href=\"https:\/\/scrapad.com\/en\/materials\/iron-steel\/\" target=\"_blank\" rel=\"noreferrer noopener\">iron<\/a> and carbon to create even stronger and more versatile metals.<\/p>\n\n\n\n<figure class=\"wp-block-table aligncenter\"><table><tbody><tr><td><strong>Material<\/strong><\/td><td><strong>Brinell hardness (HB)<\/strong><\/td><\/tr><tr><td>Tungsteno<\/td><td>250<\/td><\/tr><tr><td>Titanio<\/td><td>200<\/td><\/tr><tr><td>Hierro colado<\/td><td>175<\/td><\/tr><tr><td>Acero<\/td><td>150<\/td><\/tr><tr><td>Bronce<\/td><td>100<\/td><\/tr><tr><td>Aleaciones Al endurecidas<\/td><td>90<\/td><\/tr><tr><td>Zinc<\/td><td>30<\/td><\/tr><tr><td>Aluminio recocido<\/td><td>20<\/td><\/tr><tr><td>Plomo<\/td><td>4<\/td><\/tr><\/tbody><\/table><\/figure>\n<\/div>\n<\/div>\n\t<\/section>\n    \n\n    <div class=\"c-container c-post--related\" style=\"background-color: #F7F5F2; --xsPadding: 40px 25px 40px 25px; --smPadding: 40px 25px 40px 25px; --mdPadding: 40px 25px 40px 25px; --lgPadding: 72px 100px 72px 100px; --xlPadding: 72px 100px 72px 100px; --xxlPadding: 72px 100px 72px 100px;\">\n        <div class=\"container\">\n            <h3 class=\"c-article__side__heading\">Other posts that may interest you\u2026<\/h3>\n        <\/div>\n        <div class=\"scrapad-blocks-related glide\" data-autoplay=\"4000\" data-views-desktop=\"3\" data-views-tablet=\"2\" data-views-mobile=\"1\" data-mode=\"slider\">  \n            <div class=\"container glide__track\" data-glide-el=\"track\">\n                <div class=\"row slider-mobile glide__slides\">\n                                                                         \n                            <div class=\"col-12 col-lg-6 glide__slide\">\n                                    <div class=\"c-blog__item\">\n        <a href=\"https:\/\/scrapad.com\/en\/blog\/differences-between-brass-and-bronze\/\" class=\"c-blog__item--inner\">\n            <div class=\"c-blog__item__header\">\n                <div\n                    class=\"c-blog__item__image\"\n                    style=\"background-image: url(https:\/\/scrapad.com\/wp-content\/uploads\/2025\/01\/laton-bronce.jpg;\"\n                ><\/div>\n                <\/div>\n                <div class=\"c-blog__item_body\">\n                    <h4 class=\"c-blog__item__title\">Differences between brass and bronze<\/h4>\n                    <div class=\"c-blog__item__meta\">\n                        <span class=\"c-blog__item__date\">29\/01\/2025<\/span>\n                    <\/div>\n                <div class=\"c-blog__item__desc\">\n                    <p>In the manufacturing industry it is common to use metal alloys such as bronze and brass.
