class="khcont8"><div> 紫銅管“一半海水一半火焰” </div> <div> 國銅材出口減少，而原材料進口增加，原材料庫存增加，成本對銅價的支撐減弱。市場銅材庫存有增加，在需求沒有回暖的大背景下，銅材出口減少更是雪上加霜! </div> <div> 當(dāng)前下游需求整體偏好，操作上螺紋銅偏多思路;前期螺紋多單可適當(dāng)逢高分批出場，因當(dāng)前螺紋4000附近高點追多恐有回調(diào)風(fēng)險可暫時觀望;盤前分析僅供參考，銅材若盤走勢有變，靈活調(diào)整持倉狀態(tài)。 </div> <div> 11月以來，在需求的強勁推動下，國內(nèi)銅材價格屢次創(chuàng)出新高，粗銅產(chǎn)量也高位運行。機構(gòu)分析師陳克新指出，陳克新稱，2021年全國銅材消費需求將繼續(xù)增長。其中，粗銅表觀消費量預(yù)計將會超過10.6億噸，增幅在4%以上。預(yù)計全年粗銅直接出口量(銅材折算)8000萬噸左右，出口水平由降轉(zhuǎn)升。上述兩個方面相加，預(yù)計2021年中國全部粗銅需求量或?qū)⑦_到11億噸，比上年增長5%左右。 </div> <div> 季節(jié)因素影響正在逐步兌現(xiàn)當(dāng)中，尤其在期貨深貼水的情況下，銅廠利潤驅(qū)動力量偏強，生產(chǎn)積極性較高，疊加北材南下腳步加快，增加了南方庫存消化的壓力，市場正在向銅廠庫存增量，社會去庫明顯放緩過渡。 </div> <div> 短期來看，在需求尚在的情況下，原材料價格堅挺對市場仍有支撐，市場調(diào)整空間暫時不大，但隨著需求減弱腳步的加快，要警惕需求反向打壓原料價格的可能，動態(tài)觀察供需矛盾的轉(zhuǎn)化。 </div></div><p><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/214/1389/202402220837237310.jpg"

style="font-size:14px;font-family:微軟雅黑;font-weight:400;color:#000000;font-style:normal;"> 為了提高重慶黃銅棒耐腐蝕性里面需要加入什么元素 </div> <div style="font-size:14px;font-family:微軟雅黑;font-weight:400;color:#000000;font-style:normal;"> </div> <div style="font-size:14px;font-family:微軟雅黑;font-weight:400;color:#000000;font-style:normal;"> <br /> </div> <div style="font-size:14px;font-family:微軟雅黑;font-weight:400;color:#000000;font-style:normal;"> 黃銅中由于含鋅量不同，機械性能也不一樣，銅的機械性能隨含鋅量不同而變化的曲線。對于α黃銅，隨著含鋅量的增多，σb和δ均不斷增高。對于（α+β）黃銅，當(dāng)含鋅量增加到約為45%之前，室溫強度不斷提高。若再進一步增加含鋅量，則由于合金組織中出現(xiàn)了脆性更大的r相（以Cu5Zn8化合物為基的固溶體），強度急劇降低。（α+β）黃銅的室溫塑性則始終隨含鋅量的增加而降低。所以含鋅量超過45%的銅鋅合金無實用價值。 </div> <div style="font-size:14px;font-family:微軟雅黑;font-weight:400;color:#000000;font-style:normal;"> 普通黃銅的用途極為廣泛如水箱帶、供排水管、獎?wù)?、波紋管、蛇形管、冷凝管、彈殼及各種形狀復(fù)雜的沖制品、小五金件等。隨著鋅含量的增加從H63到H59，它們均能很好地承受熱態(tài)加工，多用于機械及電器的各種零件、沖壓件及樂器等處。 </div> <div style="font-size:14px;font-family:微軟雅黑;font-weight:400;color:#000000;font-style:normal;"> 為了提高黃銅的耐蝕性、強度、硬度和切削性等，在銅-鋅合金中加入少量（一般為1%～2%，少數(shù)達3%～4%，極個別的達5%～6%）錫、鋁、錳、鐵、硅、鎳、鉛等元素，構(gòu)成三元、四元、甚至五元合金，即為復(fù)雜黃銅，亦稱特殊黃銅。 </div> <div style="font-size:14px;font-family:微軟雅黑;font-weight:400;color:#000000;font-style:normal;"> 鋅當(dāng)量系數(shù)復(fù)雜黃銅的組織，可根據(jù)黃銅中加入元素的“鋅當(dāng)量系數(shù)”來推算。因為在銅鋅合金中加入少量其他合金元素，通常只是使Cu-Zn狀態(tài)圖中的α/（α+β）相區(qū)向左或向右移動。所以特殊黃銅的組織，通常相當(dāng)于普通黃銅中增加或減少了鋅含量的組織。例如，在Cu-Zn合金中加入1%硅后的組織，即相當(dāng)于在Cu-Zn合金中增加10%鋅的合金組織。所以硅的“鋅當(dāng)量”為10。硅的“鋅當(dāng)量系數(shù)”，使Cu-Zn系中的α/（α+β）相界顯著移向銅側(cè)，即強烈縮小α相區(qū)。鎳的“鋅當(dāng)量系數(shù)”為負值，即擴大α相區(qū)。 </div> <div style="font-size:14px;font-family:微軟雅黑;font-weight:400;color:#000000;font-style:normal;"> 特殊黃銅中的α相及β相是多元復(fù)雜固溶體，其強化效果較大，而普通黃銅中的α及β相是簡單的Cu-Zn固溶體，其強化效果較低。雖然鋅當(dāng)量相當(dāng)，多元固溶體與簡單二元固溶體的性質(zhì)是不一樣的。所以，少量多元強化是提高合金性能的一種途徑。 </div></div><p><img
