根据废钢的三种来源并结合我国下游用钢行业具体情况及历史特点，预计到2020年我国废钢产生量将达到2.8 亿吨，而其中增量的8000 万吨全部来自老旧废钢。到2025 年，我国废钢产生量将超过4 亿吨。届时如果粗钢产量不变的情况下，能够满足国内50%钢铁生产的原料需要。同时，废钢的产生量大大高于美国(8000 万吨)等发达国家。

本周上证综合指数上涨1.72%，钢铁板块上涨0.16%。周内钢价先抑后扬，主要源于冬储逐步启动。目前钢铁下游实际消费随着春节临近已经逐步进入传统淡季，市场价格波动主要来自于产业链的冬储行为。若产业链对后期乐观，则会加大开春前的资源储备，相应淡季钢价相对较强，但对旺季来临不利。相反若相对谨慎，则淡季钢价可能偏弱，而旺季钢价弹性更足。

Aluminum casting is a process of melting aluminum and injecting it into a hollow mold to get the desired shape. Aluminum castings are used in numerous applications due to multiple advantages like high tensile strength, molded inserts, fine surface finish and high heat resistivity. Aluminum cast components are used to manufacture subassemblies of vehicles, planes, and trains. These castings are also used in industries such as mining, construction, and electrical and electronics. The high demand for aluminum castings from small appliance part manufacturers and the automotive and machinery industries will boost the growth of the global aluminum casting market during the forecast period. The growing demand for lightweight and fuel-efficient vehicles is also a major factor contributing to the growth of the market. Casting products are manufactured using the following methods

本周钢价快速回调，成材和钢坯价格均有不同程度回落，随着全国各地近期雨雪天气增多，陕西，安徽，河南等地普降大雪，钢材成交寡淡，贸易商冬储情绪也逐步延后，钢材库存整体快速积累，周升41.92 万吨，螺纹增长32.55 万吨，近期一些年末检修高炉逐步复产，高炉开工率连续两周回升，潜在供给快速上升，使得商家挺价较为艰难，但我们认为当前回调属于季节性因素，往期十二月，一月也处于钢价回调淡季，冬储时间一般也在1 月下旬逐步展开，价格的可接受程度成为冬储关键，我们认为钢价在3800-4000 元/吨水平可能会给予贸易商更多做库存信心，库存由被动补库向主动补库过度仍需等待。

需求端，2017 年1-11 月，房地产开发投资完成额累计同比增长7.5%，增速较1-10 月下降0.3 个百分点，1-11 月基建投资完成额累计同比增长15.83%，增速较1-10 月下降0.02 个百分点。2018 年1 月，天气渐冷叠加年终临近，部分工地陆续停工，行业需求季节性减弱；但随着冬储行情或正逐渐开启，短期内需求弱势有望得到改善。供给端，本周全国高炉开工率、河北地区高炉开工率小幅上升，但仍处于低位
