This invention discloses a 6-series energy-absorbing aluminum alloy and its manufacturing method. The aluminum alloy, by mass percentage, comprises: Mg: 0.50–1.20%, Si: 0.40–1.00%, Mn: 0.15–0.95%, Cr: 0–0.25%, Fe: 0.15–0.45%, Ti: 0.015–0.30%, and Cu: 0.10–0.70%; wherein the Mg / Si mass ratio is ≥0.85 / 1, and the total content of Mn+Cr+Fe is ≤1.2%; it also includes an AlTi5C0.25 grain refiner and impurities with a content not exceeding 0.15%, with the balance being Al. This invention optimizes and precisely designs the content of the main alloying elements in the alloy, and introduces TiC nanoparticles using the AlTi5C0.25 grain refiner, enabling the aluminum alloy profile to possess both high strength and excellent crushability.

The application discloses an oral care toothpaste containing snake lily original medicinal material powder and a preparation method thereof, and belongs to the oral care preparation field. The core innovation is that the snake lily original medicinal material superfine powder prepared by a specific process is used as a core component, and a plurality of auxiliary materials are compounded to form a synergistic system, so that the effects of analgesia, anti-inflammation, caries prevention and anti-allergy are achieved; the snake lily original medicinal powder is treated through raw material screening, vinegar preparation detoxification, superfine crushing and multi-step coating embedding process, so that the toxicity and bitterness are effectively reduced, and the active component extraction efficiency is improved. The application solves the problems of the existing anti-inflammatory and analgesic toothpaste, such as large side effects and limited effects, and provides a new scheme for oral care.
