Alumina ceramics have many advantages.<\/p>\n

They have excellent insulation, low high-frequency loss but good high-frequency insulation, heat resistance, small thermal expansion coefficient, high mechanical strength, and good thermal conductivity<\/strong>. Alumina ceramics have a high hardness, and the Rockwell hardness of alumina is HRA80-90<\/strong>, and the hardness is only inferior to that of diamond, far exceeding the wear resistance of wear-resistant steel and stainless steel. Alumina ceramics are also abrasion-resistant<\/strong> and ideal for wear-resistant applications. They are lightweight<\/strong> and have a wide range of applications, for example:<\/p>\n

They are used in the electronics industry for passive components such as interconnection, resistances, and capacitors<\/strong> and are specifically employed in applications such as substrates for hybrid circuits, multi-layer interconnection circuits, materials for type II condensers, and hyper frequency resonators (mobile phones)<\/strong>. Alumina ceramics are also used in the manufacture of textile wear parts and knives<\/strong> due to their extreme hardness and wear resistance. They are used widely in acid-resistant pump impellers, pump bodies, acid-carrying pipe linings, and valves<\/strong> because of their excellent chemical stability. Alumina ceramics are also used as an insulation material<\/strong> for electrical components.<\/p>\n

Alumina ceramics are brittle because of excellent compression strength and low bending strength. Ceramics exhibit a linear elastic behavior and low fracture toughness, causing them to break without warning. The risk of ceramic fracture is determined by the initial flaws of the ceramic. However, alumina ceramic is light and its density is 3.5g \/ cm3, which is only half that of steel, which can greatly reduce the equipment load. Alumina ceramic is resistant to high temperature and can be used for a long time at a high temperature of 1600 degrees. Alumina ceramics have strong corrosion resistance.<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ admin_label=”Footer” _builder_version=”4.19.5″ _module_preset=”default” background_color=”#000000″ background_enable_pattern_style=”on” background_pattern_style=”tufted” background_pattern_color=”rgba(255,255,255,0.18)” min_height=”644.5px” global_module=”176″ saved_tabs=”all” collapsed=”on” global_colors_info=”{%22gcid-b2777ccc-45bf-4762-b379-294426a7f0ff%22:%91%22background_color%22%93}” theme_builder_area=”post_content”][et_pb_row column_structure=”1_2,1_2″ use_custom_gutter=”on” gutter_width=”1″ make_equal=”on” _builder_version=”4.19.5″ _module_preset=”default” custom_padding=”0px||0px||true|false” border_width_all=”1px” border_color_all=”#3E3E3E” global_module=”273″ saved_tabs=”all” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”1_2″ _builder_version=”4.19.0″ _module_preset=”default” custom_padding=”40px|40px|40px|40px|true|true” custom_padding_tablet=”30px|30px|30px|30px|true|true” custom_padding_phone=”20px|20px|20px|20px|true|true” custom_padding_last_edited=”on|tablet” border_color_all=”#3E3E3E” border_width_right=”1px” border_width_right_tablet=”0px” border_width_right_phone=”” border_width_right_last_edited=”on|tablet” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.19.5″ _module_preset=”b327cbe4-b1d5-4b66-ad37-40c8f2f061ba” header_2_font=”Michroma||||||||” header_2_font_size=”48px” header_2_line_height=”1.2em” background_layout=”dark” custom_margin=”||30px||false|false” header_2_font_size_tablet=”32px” header_2_font_size_phone=”20px” header_2_font_size_last_edited=”on|desktop” global_colors_info=”{}” theme_builder_area=”post_content”]
