Part of the refractory metals group, it is widely used as a minor alloying component, and is also used to produce a range of alloys prized for high melting points, strength and ductility. Alloyed with other metals, tantalum is used in carbide tools for metalworking equipment and in superalloys for jet engine components, chemical process equipment, nuclear reactors, missile parts, heat exchangers, tanks and vessels. Because of its ductility, tantalum can be drawn into fine wires or filaments used for evaporating metals such as aluminium, and because it resists attack by body fluids and is non-irritating, it is widely used for surgical instruments and implants.<\/p>\n<p>Tantalum is inert against most acids except hydrofluoric acid and hot sulfuric acid; hot alkaline solutions will also cause it to corrode. This makes it a useful metal for chemical reaction vessels and pipes handling corrosive liquids, and heat-exchanging coils for steam heating of hydrochloric acid are commonly made from tantalum. Historically, tantalum was extensively used in ultra-high-frequency electron tubes for radio transmitters \u2014 its ability to capture oxygen and nitrogen by forming nitrides and oxides helped sustain the high vacuum needed inside the tubes.<\/p>\n<div class=\"so-callout\">\n<h4>Key Properties &amp; Applications<\/h4>\n<ul>\n<li>Rare, hard, highly corrosion-resistant refractory metal<\/li>\n<li>Resistant to most acids except hydrofluoric and hot sulfuric acid<\/li>\n<li>Ductile enough to draw into fine wire and filament<\/li>\n<li>Biocompatible \u2014 widely used in surgical instruments and implants<\/li>\n<li>Used in jet engines, nuclear reactors, missile parts, heat exchangers and chemical process equipment<\/li>\n<\/ul><\/div>\n<h3>Tantalum-Tungsten Alloy Variants<\/h3>\n<p>Tantalum-tungsten alloys belong to the refractory metals group, retaining useful physical and chemical properties even at high temperatures. Their performance combines the strengths of both elements: tungsten, which has the highest melting point in the periodic table, and tantalum, prized for its corrosion resistance.<\/p>\n<div class=\"so-table-scroll\">\n<table class=\"so-spec-table\">\n<tr>\n<th>Variant<\/th>\n<th>Tungsten Content<\/th>\n<th>Trade Name<\/th>\n<th>Characteristics<\/th>\n<th>Example Applications<\/th>\n<\/tr>\n<tr>\n<td>Ta \u2013 2.5% W<\/td>\n<td>~2\u20133% W, plus 0.5% Nb<\/td>\n<td>Tantaloy 63<\/td>\n<td>Good corrosion resistance, performs well at elevated temperatures<\/td>\n<td>Piping in chemical industries<\/td>\n<\/tr>\n<tr>\n<td>Ta \u2013 7.5% W<\/td>\n<td>~7\u20138% W<\/td>\n<td>Tantaloy 61<\/td>\n<td>High resilience modulus while retaining refractory properties<\/td>\n<td>High-stress refractory components<\/td>\n<\/tr>\n<tr>\n<td>Ta \u2013 10% W<\/td>\n<td>~9\u201311% W<\/td>\n<td>Tantaloy 60<\/td>\n<td>Less ductile and less plastic than the other variants<\/td>\n<td>Aerospace components, furnaces, nuclear plant piping<\/td>\n<\/tr>\n<\/table><\/div>\n<p>  <\/main><\/p>\n<\/div>\n<p><script>\njQuery(document).ready(function($){\n  $('#so-acc-main').on('click', '.so-acc-btn', function(){\n    var $btn = $(this);\n    var $sub = $btn.next('.so-sub1');\n    var isOpen = $btn.hasClass('soopen');\n    $('#so-acc-main').find('.so-acc-btn').removeClass('soopen');\n    $('#so-acc-main').find('.so-sub1').removeClass('soopen');\n    if(!isOpen){\n      $btn.addClass('soopen');\n      $sub.addClass('soopen');\n    }\n  });\n  $(document).on('click', '.so-acc-btn2', function(){\n    var $btn = $(this);\n    var $sub = $btn.next('.so-sub2');\n    $btn.toggleClass('soopen');\n    $sub.toggleClass('soopen');\n  });\n});\n<\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Product Categories Pure Titanium &amp; Alloys &#9660; About Titanium Titanium Tube and Pipe Titanium Strip, Sheet &amp; Plate Titanium Bar and Rod Titanium Welded Wire and Wire Titanium Foil Titanium Forging Titanium Flange Titanium Pipe Fittings Titanium Casting Titanium Fastener Titanium Elliptical \/ Spherical Head Titanium Machining Parts Titanium Clad Plate Titanium Clad Copper Bar<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-7037","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/pages\/7037","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/comments?post=7037"}],"version-history":[{"count":1,"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/pages\/7037\/revisions"}],"predecessor-version":[{"id":7038,"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/pages\/7037\/revisions\/7038"}],"wp:attachment":[{"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/media?parent=7037"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
