2021年上半年受益于旺盛的市场需求，钢价大幅上涨，钢铁行业上市公司营收和净利润均大幅增长，行业进入十年来最景气的一段时期，钢铁企业股价大幅走高。2021 年下半年，由于房地产等行业投资增速放缓，钢铁需求有所减少，钢铁板块整体表现不佳。进入2022 年，“稳增长”政策开始发力，基建、房地产建设有望带动钢铁需求逐步回升。

下游需求持续旺盛，助力锂行业景气度提升。新能源领域景气高涨之下，锂产业链上下游企业开工率快速提升，下游增产、补库等行为快速拉动对锂盐的需求。据美国地质调查局统计，目前电池为锂下游最大需求领域，达到74%，未来锂行业需求拉动将主要来自于各类锂电池的规模扩张。

Nichrome alloys are used for architectural purposes such as lead for water pipes, roofing, and windows. Stainless steel is expensive and is used as the primarily metal ,where potential for corrosion is high. An extensive use of stainless steel was for the construction of the Chrysler Building. Nichrome is used in gears, drive shafts, special vehicles for low temperature, or high wear uses. It is also used in special engineering uses. Nichcrome alloys are mainly used for electric resistance heating. They are highly electric-resistant, have good strength and ductility at operating temperatures, etc. These properties make them suitable for use in electronic appliances. Nichrome alloys are corrosion-resistant. The anti-corrosive degree of this steel is determined by the surface condition of the metal as well as by the composition, temperature, and concentration of the corrosive agent. The corrosion-resistant steel is mostly used in aircraft construction which has 18% chromium and 8% nickel content.

Establishments described in this report are primarily participating in the weathering steel market. Weathering steel, often referred to by the genericised trademark COR-TEN steel and sometimes written without the hyphen as corten steel, is a group of steel alloys which were developed to eliminate the need for painting, and form a stable rust-like appearance after several years' exposure to weather.

锂价在 2022 年下半年上涨预期较强，但受产业链库存累积等因素影响，我们预计锂价后市涨幅或有限。我们判断锂价拐点或在 2023 年到来，价格或高位回落，2024 年随着供应过剩压力增大，锂价将显著下行。锂板块行情进入后期，原料自给率高或持续提升的企业仍为首选。推荐赣锋锂业和盐湖股份，建议关注天齐锂业、中矿资源、永兴材料。

5 月以来黄金珠宝终端零售逐步修复：1）5 月零售额同降15.5%、已较4 月的-26.7%明显收窄，预计重点公司下半年修复幅度大于行业。2）5 月线上珠宝消费环比修复、6 月同比实现较快增长。复盘20 年，疫后需求现回补、6 月线上数据初步验证。本轮疫情望加速行业洗牌、龙头集中度持续提升，Q2 疫情影响业绩预计仍承压、看好Q3 基本面及估值修复行情、建议关注周大福、周大生、潮宏基。

2022 年5 月印度培育钻石进口/出口额同比+45.95%/+137.34%，行业高景气度持续验证。

基本金属：国内经济数据环比改善，美联储大幅加息工业金属受美联储大幅加息影响，价格明显回落。产业基本面呈现低库存、国外供给受限，需求端将受益于国内经济环比改善供需紧平衡格局将对价格构成一定支撑。铝加工：新能源汽车渗透率提升，铝热传输材料需求向好在轻量化、电动化背景下，铝材作为汽车热传输材料性价比凸显，铝合金广泛应用于汽车热交换系统。据统计，一辆新能源汽车铝热传输材料用量可达20-25KG，比传统燃油车高出10KG/辆。目前全球汽车行业铝钎焊复合材料市场空间约为120万吨/年；远期看全球新能源车渗透率提升有望使铝热传输材料需求量翻倍。
