Problems solved by technology

Stainless steel is stable under normal conditions and will not cause any harm to health, but if it is in contact with salt (salt-containing food) for a long time and is not cleaned in time, it will produce hexavalent chromium, which is poisonous

Abstract

The invention provides a low-cost titanium alloy panel applied to titanium dinner plates and a preparation method of the low-cost titanium alloy panel. The titanium alloy panel is made of, by mass percentage, 0.5-1.5% of Al, 0.5-1.5% of Fe, 0.10-0.20% of O, less than 0.02% of C, less than 0.008% of N, less than 0.0015% of H and the balance Ti. The titanium alloy panel has the beneficial effects of being non-poisonous and harmless to the human body and is quite suitable for manufacturing the dinner plates; a certain proportion of Fe and Al are added, and thus a low-cost titanium alloy material is obtained; and by means of the panel obtained by rolling the titanium alloy material, material cost can be lowered, and in addition, the low-cost titanium alloy panel is non-poisonous and harmless to the human body and quite suitable for manufacturing the dinner plates.

Description

technical field [0001] The invention belongs to the technical field of titanium alloy material preparation, and in particular relates to a low-cost titanium alloy plate used in titanium meals and a preparation method thereof. Background technique [0002] Food is the most important thing for the people, and three meals a day must be served on a plate. The materials of dinner plates on the market are roughly aluminum, iron, and stainless steel. Aluminum is easily soluble in acid, alkali, salt, and brine. Aluminum dissolved in food and entering the human body can destroy adenosine triphosphate in the human body, which is responsible for the energy conversion of cells, thereby hindering the energy conversion process of human cells. Iron is easy to rust Iron rust reacts with oxygen atoms in the air to form iron oxide, and the human body absorbs too much iron oxide, which will cause great damage to the liver of the human body. Stainless steel is stable under normal conditions a...
